So, you want a pet
frog...
Before you run out to the nearest pet store or pond there are
several things you should consider.
Getting a frog shouldn't be considered all that different
from
getting a cat or dog. It can be a lot of work, and you need
to
think about what you're going to do when you skip town for a
week,
and so forth.
Also, frogs aren't like goldfish in that they can live for a
very
very long time! Don't believe me? check out some of
these
statistics
of longevity of frogs in captivity
You
may need a special license to keep frogs in some countries. I
hear that in Australia it is actually very difficult to obtain
an
amphibian license, and people who keep frogs without such a
license
can get fined heavily for it. You should definitely check to see
if
there are any special laws pertaining to keeping frogs in your
area
before you get one as a pet!
Here's a few things to consider when making
choices:
Frogs Can Be a Lot of
Work
Frogs need to be fed on a regular
basis.
Keep in mind where your food source is going to be. Generally
speaking, this isn't going to be as easy as picking up a package
at
your local grocery store! In addition, if you get a frog that
eats
live bugs, expect to have a few stray bugs running around the
house
now and then! The larger frogs can be even more work...Many of
the
larger species feed on mice and this can be a less than fun
experience if you aren't prepared for it! Frog tanks need to
be
well cleaned to prevent illness. For more information on this
topic, visit the Frog
Doctor
page to read about frog health. Also, keep in mind that each
pet
has special needs for Housing. You can read about setting up
a
terrarium for your pets in the Housing Your Pet
Frog page.
Active Frogs
Probably one of the biggest mistakes
I
hear about is people who go out and buy a "cool-looking" frog
which
then proceeds to eat, sleep, and generally sit like a lump of
clay.
The reality is, a lot of frogs don't really do much, and they
aren't exactly something you can snuggle up with either, so
you
need to keep that in mind when choosing an appropriate pet.
Frogs
may be cute or grotesque, but you can't teach them tricks,
take
them for walks, or make them speak on command. Frogs which
aren't
particularly active will quickly become a boring pet. The
novelty
will wear off and you'll be left with a blob that eats a lot.
When
looking for a pet frog, particularly for the beginner, I
strongly
urge you to choose ACTIVE breeds. This means, search for a
species
that doesn't just sit around all day. Aquatic frogs, certain
treefrogs, and the less "fat" frogs are better
choices.
Never get a Frog You
Don't
Know
There are many many species of
frogs,
and many have very individualized pet care needs. Some frogs
need
to hibernate during the winter, others do not. The pet care
needs
will change everything from what you need as far as tank set-up
to
what you have to feed them. In addition, many frogs look
really
really cute in the stores, and then you bring them home and in
a
few months they've grown in monstrous proportions and it
isn't
nearly as nice as you thought it was going to be:
A personal example:
I saw the cutest little frogs in the pet store called "Pixie
frogs"- wow! They were these tiny little green things (almost
an
inch long in size) and even their name was cute....
The next day I went to an Annual Reptile and Amphibian show
that
took place at out local Science And Industry Museum...there I
saw
that those same sweet little frogs that I saw in the pet store
the
day before GROW to become these incredibly FAT frogs about 8
inches
long!!!!! That means those cute things would have been eating
mice
and big ol' bugs and such...something I was utterly
UNprepared
for!!!
The Pixie Frog is a nickname for their Latin name,
(Pyxicephalus
adspersus), Their common name turns out to
be
The
African
Bullfrog
.

So, the moral of this story is, find out about the frog you want
to
get BEFORE you get it!
Frog Sitters
Your frog, if well cared for,
should
live for a very long time! That means you're going to run into
the
same problem everyone with pets runs into whenever they go out
of
town for vacations..."Who's gonna care for my pet while I'm
away??"
Unlike feeding a few flakes to a goldfish, the idea of live
bugs
isn't very appealing to most people who haven't been as
enlightened
about frogs as you and I have! In some cases, you can convince
a
"frog sitter" to care for your frogs if they don't actually have
to
touch the bugs. (You can read about how to make
ick-free
cricket containers on my
Dealing With
Bugs
page.) So, if you plan on getting a
frog, plan ahead as to
how vacations will be handled.
Recommended Frogs for
Beginners
For
the first frog encounter, I strongly
recommend the African
Dwarf
Frog. These guys are small,
active, cute, and about as difficult to maintain as a tank
of goldfish. You also don't have to deal with live
bugs and they can be kept in the same conditions as
goldfish for extended periods of time...(as long as there is
a
cover!) Dwarf frogs are very easy to take care of once
they've
become used to their new home. As with all fish, expect the
first
couple of weeks for adaptation time (many times pet stores
will
sell frogs that are already sick, or that are very very small
and
which may be a bit fragile in the first couple of weeks.) My
sister
had terrible luck with the baby frogs until she learned to wait
for
2 weeks before she names her new pet (Usually, by then you can
tell
if the frogs will make the long haul) The best recommendation
here
is to get them at a decent size. Avoid really skinny ones or
ones
that are as small as your pinky-nail. In addition, if the
frog
doesn't give the pet shop owner a really hard time when the
net
goes into the tank, it may indicate some initial signs of being
in
less than perfect condition.

Don't confuse these with
African
Clawed
frogs
,
which look very similar when small. The clawed frogs get
quite large and actually are illegal in some states (Like in
Oregon
and California!)

For a beginning frog owner who wants
to get the full terrestrial frog experience,
Oriental
Firebellied Toads
are
an excellent choice. These guys are
fairly simple to care for, in so far as they can survive
fairly
well off crickets with vitamin supplements, and they are
incredibly
active critters. They also don't get too large. Finally, there
are
no hibernation requirements for this species and they do well
in
temperatures that people generally are happy to have in their
homes. Unless you live in an icebox or in extremely hot
climates,
this species of frog won't need special climatization for
it's
terrarium. You'll need to find someone who can handle crickets
when
you go away on vacation for a week or more to take care of
them
though, but keep in mind crickets are much easier than frozen
mice!
(Finding a frog sitter for my Firebellies proved to be fairly
difficult for me, until I found a friend who actually
works
at the pet store where I buy the crickets and he was nice enough
to
take care of them for me while I was out of
town!)

A
good Tree Frog for beginners is the
White's Tree
Frog
.
This frog has a funny personality and seems to be
quite a popular pick. It should be warned however, that some
children bore of the whites tree frog despite its funny
personality, simply because they tend to just sit around a
lot.
(Once I even got a letter that said "Whites Tree Frog-What a
blob
of nothing!") Much of the behavior of the frogs however, can
be
traced to how much they eat (and how fat they get!). In
addition,
the Whites Tree frog is one of the few frogs that is fit to
occasionally be handled, and it certainly has warmed the heart
of
many frog enthusiasts!

In addition to dealing with crickets, the Whites tree frogs need
a
little more care than the Firebellies need, simply because
they
live best with humidity and are happiest when the tank is
sprayed
with water once or twice every day. However, as far as
Tree-Frogs
go, they are by far one of the easiest to deal with and
hardiest
species available to be kept as pets!
Frogs NOT Recommended for
the
Beginner

Poison Frogs are absolutely NOT a beginners frog.
Even though these
frogs lose their toxicity in captivity, their care is very
complicated and these fragile beings have very specific
requirements for healthy captivity. I don't even want to write
up
any care sheets because I myself am not expert enough to tackle
the
complicated procedures for proper care of such
breeds.

Expensive frogs in general should not
be a frog considered by the beginner because a frog that costs
over
50 bucks is a high investment to make when you are still
learning
about frog care. Even if you've read all there is to read
about
frog care, you really ought to start with an easier breed
before
taking on the more expensive breeds like Red-Eyed TreeFrogs
and
such.
Frogs captured in the wild should be
a frog that you KNOW, otherwise you take the risk of not
knowing
the proper temperatures, diet, etc. I often am asked about
frogs
that naturally appeared in an outdoor pond where weather
patterns
lead to pond ice-overs. I don't think it's a good idea to
"save"
frogs from an environment where they naturally occurred in
the
first place. I suspect that the types of frogs that appear in
such
climates probably hibernate in the colder months.
Frogs that get FAT,
like
Horned
(Pacman)
frogs
,
Budgettes Toads, and Bullfrogs can get to be pretty
boring as pets for the beginner.

The Budgettes toad can also pack a
good wallop of a bite when it's full grown, so watch those
fingers!
This doesn't mean you absolutely should not get some of these
for
pets, (Pac Man Frogs, for example, while somewhat "boring" to
some,
are also very hearty and not as prone to the usual frailties
of
other types of frogs) but I'd really think carefully about how
long
you're going to retain interest in this type of frog
before
you've made any sort of commitment by going out and getting such
a
pet....
- What should I feed my frog and how
much?
If
you're not sure and cannot find a caresheet on the type of frog you
have, always start with crickets.
Crickets are easy and basic. You can even make a cricket house so
you don't have to touch those icky bugs! See
Dealing with
Crickets for the Squeamish Pet Owner for
more information.
Most frogs and toads will eat all sorts of bugs and wiggly jiggly
things that most people would cringe to see crawling on their
bedroom wall at night... so if in doubt, start with crickets, and
add anything else you find them interested in eating. The big
fatties sometimes eat goldfish and guppies, and some will even eat
mice!
As for teeny tiny frogs, you can try baby crickets or flightless
flies or even live bloodworms placed in an upside down milk-cap (or
some sort of shallow dish that has a bit of water for the
worms.
For tadpoles, see the
How to Raise
Tadpoles
If you've got an aquatic frog (i.e. it stays underwater all the
time), start with frozen bloodworms or brine
shrimp.
- How
much should I feed my frogs?
This is probably one of the most
common questions that I get asked. Your best bet is to experiment
and try out how much food seems to be good for your frog. Try
dumping in 3 or so crickets per feeding session per frog, and see
whether the frogs seem to still be hungry or starts to look
underfed. Remember, frogs really do seem to have distinct
behaviors, even within a species! Some will gorge themselves on any
available tasty morsels regardless of need, while others will only
eat once in a while when hungry. Excessive feeding is not healthy
for many frogs, though some simply choose to ignore excessive food
when not hungry. Determining how much to feed the frog is often a
matter of understanding your frog's personality!
Other types of food can be tried (ex. mealworms, waxworms,
grasshoppers,etc.) But crickets seem to be the "food of
choice."
There are some guideline recommendations listed on
the
Dealing With
Bugs
- My
frog won't eat! What do I do?
Some frogs will only eat moving food.
Some may be eating but you just don't see them do it...(I have
often seen my Firebellies
sit around with crickets hopping all
over their tank and seem not to eat...yet somehow the cricket
population in my frogtank is gone within the next few days...(and
I'm positive that the crickets haven't found an escape
route!) More often than not, however, lack of appetite is a side
effect of other illness. Usually, when the frog recovers from
illness, the appetite returns. (See the
Frog
Doctor
page for more info on frog health)
The first thing to do in this case is to make very sure that the
frog's environment is clean and to administer any relevant
treatments for obvious diseases. In the meantime, you may want to
try coaxing your frog to eat by hand-feeding.
First of all, you'll need to kill a cricket or whatever your frog
usually eats, and have it ready in blunt forceps. (the kind with
round-ball tips so your frog wont hurt himself on the tips)
Case one, where things aren't totally desperate: try just wiggling
the food right in front of the frog. If this doesn't work, you may
want to force-feed it.
To do this, hold the frog in your non-writing hand, with your thumb
on the back of its' head, and your forefinger wrapped around under
its neck. (Obviously, you should be sure to wash your hands really
well both before and after this procedure!) Press firmly, but not
too hard as to squish it.
With the other hand, get a drivers license, or stiff card, and with
the rounded corner gently open the frogs mouth. When the card is in
the mouth, just press the frogs' mouth together so the card stays
in there.
Pick up the cricket (or whatever) in the forceps and by maneuvering
the card, tilt it downwards, opening the frogs' mouth. When it is
open, just place the cricket in the frog's' mouth. When the card is
pulled out of the mouth it will eat the cricket with no troubles at
all.
Be careful not to be harsh on the poor thing though, because if
it's so bad that you need to do this at all, don't forget that your
froggy buddy ain't feeling too hot in the first place!
If this doesn't help, or you'd rather not risk it yourself, I'd
suggest you bring in your froggie to visit your local vet for a
checkup.
- What do I do if I can't find bugs
small enough for my tiny frog?
For those unable to get super tiny crickets
to feed their tiny tree-frogs, one visitor wrote with this great
advice:
"My daughter went camping and brought home a couple tiny tree frogs
not more that 1/2 inch long each. We were unable to buy crickets in
our area that were small enough for them to feed on.
What we found out (actually my wife thought about it) was that we
had plenty of food for them in our own back yard. We found it on
our rose bushes ... aphids! The frogs seem to love them, and
they've been doing just fine!"
One added note though: it probably wouldn't hurt to dust the aphids
with some vitamin powder every now and then!
- Do
frogs shed?
Yes!!! Don't confuse the natural process of
growth with skin disease! I went to Poland for six weeks in the
early summer and left my frogs in the care of a frogsitter, who,
considerably nervous about undertaking the enormous responsibility
of taking watch of my dearest, fell into an absolute panic when the
African Dwarf Frogs started to shed their skin! While the African
dwarf frogs skin just comes off every now and then, other species
of frogs that don't swim underwater all their lives can look
downright alarming when they shed! When my firebellied toad was
shedding, he got into this really weird scrunched up or crouching
position, and started looking like he was bloating up (either that
or having some sort of coughing or epileptic fit) and then he
started to look like he was coughing! Shortly, though, I realized
that he was stretching himself so that the old skin would come off.
He then started to eat the skin as it was coming off! (ick) But
this appears to be a natural occurrence, and shedding seems to be
connected with both weather and growth...so don't panic if your
frog starts to shed its skin! Besides, afterwards, the frogs always
look really clean and pretty with their new skin!
- How
long will my frog live?
As
it turns out, this sort of info is very hard to come by!
There is, however, a web page dedicated to collection of data on
longevity in which there are entries by all sorts of amphibian (and
reptile) breeders about how long their particular specimens of
frogs had lived in captivity. If you want to know how long your
favorite type of frog might live in captivity, try looking it up by
species in this database: REPTILES
AND AMPHIBIANS IN CAPTIVITY - LONGEVITY HOMEPAGE:
FROGS
For some more general facts, check out the
How Long Do
Frogs Live?
page, in the Weird Frog Facts
section.
- Is
it safe to mix different species of frogs or toads in the same tank
or pond?
WHEN IN DOUBT, NO!
I can't stress this enough! Definitely some species do ok together,
but in many cases this can have deadly consequences! One visitor
wrote me with an anecdote about having a Firebellied
Toad and
a Pac Man
Frog in
the same tank. Even though the Firebelly was half the size of the
Pac Man, after 15 minutes, she returned to the tank and in horror
found the Pac Man Frog dead! The Firebellied toads have toxins in
their skin (hence the neon warning on their bellies) which, while
not harmful to humans, is quite deadly to some other species!
Similarly, Pickerel frogs, which look very much like
Northern
Leopard frogs except that their spots are more
squarish, have very toxic secretions (hence should NOT be mixed
with the similar looking Northern Leopard frogs.)
Cuban Tree Frogs have been known to EAT other types of frogs! NEVER
NEVER mix a
Cuban Tree
Frog
and
a Green Tree Frog! Some Cuban Tree frogs will even eat members OF
THEIR OWN SPECIES if they are big enough! (eeeew!)
And another thing to remember: a frog doesn't have to be bigger to
eat another frog, just hungry!
- What about hibernating
frogs?
If
you're dealing with outdoor frogs from your area, there's no reason
to "save frogs" from a temperature which they normally live
in!
But, when you import a species of frog or toad which needs to
hibernate, (or have one in your home), one method for dealing with
creating the cold environment is refrigeration! Frogs and toads are
the only species that can be hibernated reliably in a refrigerator,
although it's recommended that you only attempt it with the
hardiest species. One visitor wrote me with the following useful
advice:
"It was really easy with the toads I have (Woodhouse toads),
although I admit I was a little nervous about it. I live in an
apartment with a little fenced in porch, and they lived out there
all summer. I put some plastic storage boxes out there filled with
dirt, peat moss, and vermiculite for them to bury in. When it
started getting colder, they would bury. When it started getting
below 38 or so, I brought the tubs in and put them in the
refrigerator. I drilled holes in the lids and closed them in. They
need to have fresh air in the refrigerator every day, and the soil
needs to be moist, but they are doing just fine. I can see their
white bellies in the bottom. They move around some in there, so I
know they are doing okay. The temperature is not supposed to get
below 38 or 39 degrees. When we are out of town, I just stick
something in to keep the door from shutting completely so they will
get fresh air. It seems to be working just fine!
For frogs or toads housed indoors, the process is probably a bit
more tricky. You have to slowly cool them down and reduce their
photoperiod over a couple of weeks, and stop feeding them (it is
amazing how little they eat when they start cooling down.) Then you
hibernate them in wooden or plastic tubs of dirt like I did. I am
not sure how you are supposed to go about cooling them off
gradually like that, which is why I have not tried it with my
indoor toad.
I am also not sure how it works with frogs, who are more aquatic
than toads, but the books suggest it can be done!"
Your best bet would be to consult a book on keeping pet frogs
before attempting this yourself.
- Is
my frog pregnant? How can I tell if my frog is
pregnant?
I
get this question surprisingly often...
First of all, the word pregnant in the case of frogs seems fairly
misleading.
Frogs and toads are in a sense, more like birds. They don't get
pregnant and then have a baby...
They lay eggs.

Sometimes, a frog gets a little-bit
bloated looking before it lays eggs. I guess this can be sort-of be
called pregnant.
To the right are two pictures of a so-called "pregnant" dwarf frog.
Click on them to see them full sized. Photo courtesy of Karen of
the Aquababies website)
For more information, see the Life Cycle of a
Frog in
the Weird Frog Facts section.
How can you tell if your frog is pregnant? Well, if you use the
term in this loose sense, it could be a slight fattening around the
tummy. Often times though, you really won't be able to tell. If you
are seeing really HUGE bloating, your frog is more likely
sick...Consult The Frog
Doctor section for more info.
Of course, with so many diverse species of frogs and toads, there
are also exceptions to the rule (as there are to almost all the
rules for frogs and toads!)...Most frogs like tree-frogs, dwarf and
clawed frogs, and common toads, and so forth don't fall into
the "exotic" category...so it's highly unlikely that your PET frog
will be one that actually becomes "pregnant" in the true sense of
the word...
However, of the exceptions, there are some, like the Costa Rican
rain frog that lay eggs with fullgrown tiny froglets in
them...others, like the Surinam Toad, lay eggs which then
get rubbed into the folds of their skin and then indeed, tiny
froglets emerge... See
Weird Frog
Facts
for
other strange frog breeding stories.
- If
I put pesticide on my lawn, will it hurt local
frogs?
Hmmm....
Well...putting poison on your lawn probably isn't the best idea if
you want happy frog neighbors... Come to think of it, if you
already have frogs on your lawn, chances are a lot of you bug
problem should already be fixed! However, in answer, yes- most
likely pesticide will hurt the frogs.
Further reading is available on the subject in the FROGLOG
(Declining Amphibian Populations Task Force)
newsletter:
The Ghost of Pesticides Past?
You might consider alternatives, such as getting a package of
ladybugs and sprinkling them on your rose bushes (they eat your
aphids without hurting the garden!)
- Is
it safe to bring frogs to my outdoor
pond?
In
general yes, AS LONG AS the frog you are bringing in is NATIVE to
your area! Many areas are suffering the unforeseen consequences of
importation of non-native species of frogs. Cuban Treefrogs hitched
rides on banana boats and came to the U.S. Now they are rapidly
devouring every last American Tree Frog. Australia has suffered
similar problems. In California, Clawed frogs aren't even legal as
pets, because some got loose in the Californian water system and
now those critters are eating EVERYTHING in sight.
- How
do I get rid of the frogs in my yard?
First, if the reason you want to get
rid of them is because of noise, take a moment to realize just how
many mosquito bites you ARE NOT getting thanks to these big-eyed
creatures! Most gardeners will tell you what a blessing it is to
find a toad living in the garden because these are the best natural
pesticide you can imagine! (They don't hurt plants, and eat the
bugs!) Plus, you'll probably find that frogs make noise only for
short seasons and usually folks get used to it and are sad when the
breeding or rainy season ends and they don't get to hear the funny
croaking anymore.
However, if the reason you are asking is because of a other pets
such as a dog, I would FIRST look into training the dog NOT to
treat toads as toys, as it can be
DEADLY Cats are usually smarter.
Finally, if you insist, I was able to scrounge a
link:
eHow to Rid Your Garden of
Toads
What if it's a matter of not completely ridding the yard but of at
least diverting the frogs from the pool, garage, or equipment that
they might be getting themselves into? Well, actually, there may in
fact be a good answer for that! A man in Florida has invented "Tree
Frog Hotels," small houses built of compressed paper board that
looks similar to a bird house, but serve as the daily home for up
to four tree frogs. They are now attracting visitors and not only
are they keeping the frogs out of the pool and pool equipment in
his yard, they are also helping to keep them safe and sheltered.
He's gotten so much interest in these hotels that he has actually
set up a website where you can get more info:
Tree Frog
Hotel.
There were quite a few news stories about the guy
-
you
can read one of the articles here
- How
do I figure out what kind of frog I've
got?
Probably one of the most common questions I
get is people that write to me saying that they found a frog and
want to know what kind it is. Please realize that there are around
3,900 species of frogs in the world! Some frogs look very different
yet they are the same kind, others look similar but are different
kinds of frogs. There is simply no way I could answer your
question, but what I would recommend is this:
Check in local regional guides (nature guides
and so forth) to see what sorts of species are native to your
area....then at least you've narrowed down the possibilities. Often
you'll find nature guides in bookstores and libraries in sections
dealing with nature hikes in the area.
- How
do I tell if my frog is male or
female?
I
wish I could give you a standard test you could try here.
Unfortunately, there's really no easy way to tell. It really
depends on what type of frog you have.
- Some frogs the female is bigger and
darker. Some frogs, its the opposite!
- Some frogs have only males that sing.
If a frog has a vocal sac (the kind that blows up like a balloon)
it's very likely to be the male of the species. But, there are
species of frogs where both males and females participate in
singing and sometimes the type of song they make is what is
different.
- Some types of frogs can be told male
from female because during the mating season the males get these
little pads between the "thumb" and "forefinger" of their froggy
hands... these little pads get inflated a little and are where they
hold onto their sweethearts during snuggling activities. (Note,
these can be extremely hard to see!!)
- Another way to guess is to see which
frog is the one that hops on top of other frogs. These are usually
males...looking for females. But, don't guess that the frog
underneath is necessarily female! Often times, male frogs can't
tell either, and they'll hop on anything and everything that might
be a female, including other male frogs, rocks, logs, and even
peoples shoes!!
Wherever possible, I have added clues
to this on each frog's species caresheet. If it's not there, I
simply don't know...and you'll have to fall back on these guesses
to figure it out.
If there are any "frog experts" who have more clues, I would REALLY
appreciate hearing from you! This has got to be one of the top 10
questions I get asked!
- I
have a pet XXX frog. How do I take care of it?, what does it eat?
etc etc etc...?
Look in the
FAQ About Pet
Frogs: Species Caresheets
section. If your frog isn't listed
there, then it means I probably don't know. You might pick out a
frog with similar characteristics (for example, if its a tree frog,
look for the caresheet of a similar treefrog and use that as a
starting point.) The other option is to do a web-search on the full
name of the type of frog you have...
- My
child wants to keep a frog as a pet. Is this a good idea,
especially if the population is
declining?
There is not one answer to this question.
However, the following things should be considered. Frogs should
not be taken from public lands as these animals are there for the
public's enjoyment. While most, if not all states permit people to
keep one or two wild caught frogs, you should be aware that some
states do restrict the number that can be caught or kept. Although
it is unlikely that any frog within your child's reach will be an
endangered species, please use a field guide to check the
identification of the animal and make sure that it is one of the
common species. If you keep a frog with other species you should
not return it to the wild as it can pick up diseases and spread
them to its wild brothers and sisters. Always return a frog to the
same area in which it was captured.
- I
have a non-native pet frog that was purchased in a pet store, but
don't want to keep anymore. Can I turn it loose in the
backyard?
No;
you should not release a non-native species into your area.
There are several reasons not to do this. First, your amphibian may
not be able to survive if released into an alien habitat. It may be
unable to locate the types of food it depends upon to live. Your
local climate may be inhospitable, and it may encounter difficulty
finding shelter. It may not be able to escape unfamiliar predators.
You may also harm native amphibian species in your area if a
released non-native introduces diseases to which the native species
lack immunity. Finally, non-native species can invade and
permanently alter an ecosystem, outcompeting, crowding out, and
even killing native species. Invasive species are a major threat to
many ecosystems around the globe, and can cause serious
environmental and economic damage. (To read more about invasive
species and the threat they can pose,
click here
If you can no longer keep a non-native amphibian as a pet, consider
these options:
- ask
a local pet store if they can take it
- advertise it in a newspaper or
trading gazette
- find out if a local school would be
interested in adopting it as a class pet
- contact your local SPCA, Humane
Society, or other animal-care organization

Frog tadpoles have gotta be the favorite pet
of all time! I know more people who have dealt with tadpoles than
goldfish... but then, maybe that sais more about the people I know
than it does about pet owners in general. But I CAN tell you that
raising tadpoles can be much more than just fun- it is easy and
educational too!
Here's what you need to know for dealing with tadpoles
yourself.
- First you'll need a suitable
container, like an aquarium, fishbowl, plastic garbage bin,
paddling pool, or garden pond.
Be sure it has good shade---about 3/4 shade is ideal.
If you are planning on having a frog pond, be sure there are no
Oleanders, Pine trees or other poisonous plants near it! The fallen
needles and leaves can be toxic to tadpoles.
- Tadpoles absolutely depend on having
fresh, clean water.
If you take the water from a local stream, creek or pond, be sure
it isn't polluted. Ideally, you can get it upstream from any
suspected sources like factories, sewers, etc.
If using tap water, let it stand exposed to full sunlight for 5 to
7 days. This will allow the Chlorine to be removed by
evaporation.
If you don't have that much time, you can buy de-chlorinating drops
at your local fish-carrying pet store. But at least leave the water
out overnight, even after using the droplets.
Even a little chlorine is deadly to tadpoles.
It is always a good idea to keep a little de chlorinated water on
hand.
- What do tadpoles eat?
Well, I hear they LOVE lettuce. Boil the lettuce for 10 to 15
minutes and then drain it. Chop it up a little, and then you can
lay it on a tray to freeze it. For average home ponds, use an
icecube tray- 1 cube every couple of days should be enough. For
smaller tanks, just lay some flat on a tray and freeze it, and keep
it in a baggie in the freezer. Give the tadpoles a pinch every few
days.
Remember: too much food will get the water all dirty, and too
little will make the tadpoles get nutty and go after each other. If
your water gets dirty really fast, slow down on the feeding...and
be sure to replace the dirty water with some fresh spare
water.
The length of
frog development from egg to tadpole to frog usually takes between
6 to 12 weeks.
But it is also temperature dependant, so during cold spells it may
take a bit longer or even be suspended till the temperatures go
up.
For example, eggs laid towards the end of summer may hatch, but
tadpoles may stay tadpoles until the Spring/Summer period. So if
it's cold and your tadpoles don't seem to be growing up very fast,
it's no reason to panic.
- The
length of time a tadpole takes to develop really depends on what
kind of frog it came from! I've even heard that some tadpoles can
remain in their tadpole stage as long as 8 months, while others
only take 6 to 9 weeks! When the tadpoles start getting close to
developing legs, they will need some sort of perch so they can get
out of the water. Floating water lily leaves and branches are
ideal, but you can also create ledges using stones or even tilting
slopes of plastic in tanks.
The tilt of
the ledge may be important depending on what type of frog you have.
Young tree frogs can climb smooth vertical surfaces such as the
plastic pond liners and glass, but the ground dwelling frogs will
need a rough slope when the time comes to climb out of the
water.
At this point, if they aren't big enough to eat crickets but are
too large to eat lettuce, you can try starting them off with small
insects. A good substitute is bloodworms (live is best) which are
usually found in pet stores that carry fish. You can try feeding
them to the frogs by taking the lid of a jar and turning it upside
down. Fill the cap with a bit of warmish water and lay a bunch of
the gross wiggley worms in and usually the frogs will find them. Or
you can put the worms directly into their water...
One Frogland visitor writes, "Also, in addition to crickets and
meal worms, I have found that in the froglet/young frog stage,
aphids are a good food source. They are easily found on a certain
type of dandelion, so I just snip off a stem and place it in the
cage, and the tadpoles have a feast!"
- If
you're rearing the tadpoles outside, keep the garden well watered
and well vegetated. Young frogs will need a lot of ground cover to
hide. There is not much point in rearing frogs in a totally hostile
environment.
In tanks, the same rules apply as for full grown frogs. Afterall,
even if you're not a frog predator, they still like to hide under
plants and rocks when they can!
- Frog ponds kept year-round may
establish a permanent breeding pond. If you're worried about
mosquito problems, drop in a few 'Blue Eyes' fish. I hear they
thrive on on mosquito larvae and won't hurt the frogs. These fish
should be available from your local fish-carrying pet
stores.

How to tell what kind of frog you have
from a tadpole:
Telling what a tadpole is is very hard to
do...
About the only thing I can recommend is to find a regional guide
(like go to the library and find a book about what sorts of animals
live in your area) and often if there are frogs, they will also
show photos of what they look like as tadpoles. There really aren't
any obvious distinguishing features that separate frog types at
tadpole stage. Remember there are around 3,900 species of frogs in
the world!
If the field guides for your region don't have pictures of
tadpoles, your best bet is to wait until it becomes a frog and
compare the pictures of frogs in the guide.

Where to get Tadpoles:
I
am often asked about where to get tadpoles...
- Of
course, the most obvious option is for those who live near areas
with old ponds with frog populations.
Assuming
this is within your reach, hike on down there with a dip net and
bucket, slosh through the water and you'll be sure to net quite a
few!
And you'll probably have a pretty fun time doing it too...
(Bring galoshes!)
- However, since most of the folks
writing me with this question don't live anywhere near publicly
accessible ponds, my first thought would be to ask at the local pet
stores whether they have any contacts for getting some
tadpoles.
- A
very good place to try is looking up "POND SUPPLY" in the local
Yellow Pages...very often you will find that they carry or can
order tadpoles for you. Remember if you are going to put these in
an outdoor pond, be sure to get only native species of
frogs!
- The
other option is to try some of the online reptile and amphibian
suppliers.

EEEWW!! Frogs eat
*what*??
I love my
sweet, darling little froggies, but I have to confess that I still
have a hard time dealing with their diet. While I can deal with
slimy little amphibians, the bug scene never really appealed to me.
There are, however, ways to deal with crickets even for bug-sissies
like myself. Here are a few tips for those out there who would
prefer to make a few extra trips to the store rather than dealing
with raising hoards of bugs in their garage!
How to house icky bugs
- Making a spiffy
Container
If you plan on keeping bugs in a small container rather than
housing them in a tank, heres a great way to make a "ick" free home
for your bugs. Sometimes, you can find a similar container all
ready to go in the pet stores, but they are easy to make for
yourself.
Note: My frogs eat small crickets, so this works great on
smaller to medium sized. If you (or your pet*) have larger sized
bug needs you can probably use the same techniques, but make the
container bigger also.
*that's a joke, silly!
- Take a large sized yogurt container.
(I recommend one with at least a 2 and a half inch base.) I've
tried this with cheap tupperware but I think the plastic may have
some kind of chemicals in it because the crickets kept on dying in
there, so you should probably stick to a regular non-thick plastic
food container)
- Poke a whole bunch of holes all over
the sides of it. Use a thumbtack, so the holes are big enough for
air flow but not big enough for the cricket to eat their way out.
(yes, I did say eat their way out, these containers have
to be replaced once every few months, my last one lasted about 4
months so this isn't a very common occurance, and these containers
get kinda gross after a while, so you'll probably want to replace
them anyway.)
- Cut
a hole large enough to let out a few bugs in the lid of the
container. Best bet, cut the hole near the side of the
container. Then, just like a grated parmesan cheese dispenser, you
will be able to shake the nasty bugs out as a nice lunchtime treat
for your froggies. Mmmm, yum!!
- Get
a cork: try a rubber stopper or some sort of cork shaped item that
you can wedge into the top as a makeshift door, making sure the
cork will be able to close this door up such that even a really
strong cricket couldn't get out. On the containers that
you can sometimes buy, (they run about 1.75$, it's too bad they
aren't always as easy to find!) there's a neat top that has a
spout. If you are lucky to have such an item handy, you can
duplicate this with a second lid that fits over the first lid, so
that you simply remove the second lid, leaving the first lid with
the "escape hatch" in place on the container.
- Finally, an added but not absolutely
necessary touch: get a piece of sponge, like a long thin edge of
sponge, and clean it really, really well so there aren't any
chemicals left in it. (even new sponges tend to have a few cleaning
agents in them, so just soak them and squish out water as much as
you can...) Then, using simple needle and thread, sew the sponge
vertically to the side of your new bug container on the inside by
threading it to some of the air holes you made earlier on one side.
Now, when you go to shake out bugs, you won't get the sponge
falling all over the place either squishing and killing the bugs or
blocking the escape hatch. Also, since you should have lots of
holes even under where the sponge is, you can occasionally tip it
under a faucet and drip some water onto the side of your container
and rewet the sponge without risking any bugs getting loose.
Pretty neat, eh?

Sometimes, you can find such spiffy
containers pre-made on the market,
I used to be able to find little plastic containers that amounted
to about the same thing. I haven't seen those in ages though.
One visitor writes: "Have you ever heard of the Cricket Corral?
It is a small cricket keeper that has a wand that allows you to put
crickets in with your frogs, and not have to touch them. It also
has a place for water and gut load. It is sold by Pet Tech. If you
do a hotbot search on "pet tech" and "cricket corral" you can
probably find a place on the web that sells them. I think they are
around $20. I don't personally have one, but my younger brother has
an Anole (he saw them and loved them, wanted one and got one before
he found out what they ate), and he hates bugs too. So I got him
one of these, and he just pulls the wand out and shakes a couple of
crickets into the cage."
Another visitor wrote: "The cricket corral falls apart very
quickly and the crickets chew through the cardboard
tube."
So...there's what I know about it. You'll want to clean the
container every time you go to get more bugs. Just feed the last of
the crickets to the frogs right before you go to the bug-store, and
then run really, really hot water through the container to wash it
off before you leave. Crickets stink and it gets pretty gross if
you don't. If you have a few dead bugs left over, just set the few
crickets left free in your back yard and consider them spared. It's
better to let a few go free then be scooping gross dead floating
bugs out of your lovely frog terrarium.
- Temperature requirement for
crickets
I keep mine in a cabinet at room temperature, so they may at times
get a little colder at times and probably last longer when it's
warmer in my home. The recommended temperature for keeping live
crickets is between 75 and 85 degrees (Faranheit). However,
crickets stink so I would rather not have them
living too long in my cabinet anyway. As long as it doesn't get too
cold, or too hot, room temperature seems fine. I wouldn't recommend
keeping them outside or in a garage if it gets really chilly there
though (or if you live someplace where the temperatures reach the
high 90s!)
- Feeding your bugs before you
feed your frogs
If you're like me, you're not keeping the crickets for longer than
a week, so we don't need to worry about long term feeding here.
Generally, crickets need something damp: the sponge provides the
moisture, and you want to feed them something extra to
keep the frogs healthy. There's a calcium enriching commercial
cricket "gut" food ('cause it packs their guts full of Calcium)
that you can buy in most pet stores that is really, really
good for your froggies. I've heard that people who raise crickets
and breed them at home etc. complain that this is a good nutrition
source but very very expensive. Hmm. I guess you need to have a lot
of crickets to be of that opinion. I bought a bottle of the stuff
for about 3 bucks several months ago and I've barely made a dent in
it. If you're willing to spend 2 bucks a week on bugs, the calcium
food pellets are probably a best bet. Just drop a bunch of these
rock like items in through the escape-hatch hole and plug it up.
Make sure they get fed these special pellets the day before you
feed your frogs.
If you want to alternate and save some pellets, little pieces of
carrot or a potato wedge should do just fine. Another alternative
for feeding the crickets (and this one's kinda kooky): rabbit food.
Yep, that's what I said, rabbit food. So claims one Frogland
visitor who tells me this is what they feed them at their local pet
store! Maybe this explains why the crickets that do get loose like
to hang out near the cat-food dish at my place. (And here I thought
it was just cause they like to play with my kitty!)
If you're going to feed them some non calcium gut food, your best
bet is to sprinkle them with a calcium powder just before you dump
them in the tank with your frogs. I said sprinkle, as in
lightly dust them, not coat them like a Shake and Bake
Chicken!
- How long can crickets
last?
Well, if you raise them in a tank the way the "experts" do, then
they probably could last a lot longer. However, I find that for my
2 frogs, I go to the store about once a week and buy about 2 dozen
bugs.
If you're lucky, you can find a really cool pet store that doesnt
"count" out 24 bugs, but gives you what "looks like" that many
(which tends to be a lot more). If you store them in a place that
gets really really hot, or you overfeed them with that calcium gut
stuff, you may end up with a stinky mess of dead
crickets.
Raising Your Own Bug
Supply
If
you live far from a pet store or there isn't a pet store near you
that has convenient hours, you should probably look into the larger
size project of raising crickets at home.
I'm afraid I'm a bit too squeamish for this (it requires *eegh*
touching bugs!)
but here's a page with some useful information for those less
squeemish than me:
How Many Crickets Should I Feed My
Frogs?
This is probably one of the most common
questions that I get asked. Your best bet is to experiment and try
out how much food seems to be good for your frog. Try dumping in 3
or so crickets per feeding session per frog, and see whether the
frogs seem to still be hungry or starts to look underfed. Remember,
frogs really do seem to have distinct behaviors, even within a
species! Some will gorge themselves on any available tasty morsels
regardless of need, while others will only eat once in a while when
hungry. Excessive feeding is not healthy for many frogs, though
some simply choose to ignore excessive food when not hungry.
Determining how much to feed the frog is often a matter of
understanding your frog's personality!
Other types of food can be tried (ex. mealworms, waxworms,
grasshoppers,etc.) But crickets seem to be the "food of
choice."
This is only a recommendation, but seems to be a good starting
guideline:
Froglets and smaller than 1/2 inch:
Small sized frogs and froglets which can't
take in the smallest sized crickets can be fed bloodworms.
Generally, bloodworms are best for froglets when served live in an
overturned jar lid with some water. For small frogs, flightless
fruitflies are also a popular alternative.
1/2 to 1 1/2 inch:
Offer the little froglets 2-3 week old
crickets daily (crickets should be no longer than the width of the
froglet's head). A coating of calcium/vitamin supplement is
strongly recommended. Young frogs in particular need these
additives to grow up healthy. I have firebellies which are about 1
1/2 inches in length, and generally I dump a dozen "small" crickets
in the tank for 2 frogs once ever 4-6 days.
1 1/2 to 3 inch:
Offer 3-4 week old crickets about every two
or three days (coating less frequently- maybe once or twice a
week). You can try offering them 1 to 2 day old "pinky" mice once a
week (if your frogs will take them).
3 inches and higher:
Feed large crickets two to three times
weekly. You should reduce calcium/vitamin intake to once a week. An
excess of calcium and vitamins may cause a non-reversable kidney
disease in some frogs. You can also try "pinky" mice or early stage
"fuzzy" mice, if your frog will take them.

This evening I intended to bake the
the bread for Bread Baking Lesson Two for this site. But I forgot
to add one of the ingredients that I intended to write about in the
lesson. This left me with a perfectly viable dough, just not the
dough I wanted to use for my lesson. So I had to come up with
another use for all of the dough I had made.
When I was little, we lived in the
Mission District in San Francisco. There was a Mexican bakery there
that used to bake a beautiful alligator-shaped loaf of bread. My
wife and I were recently discussing this and came up with the idea
of trying some animal shaped loaves ourselves. Since she runs a
popular
Frog Website,
the first animal that came to mind was a frog.
Click the "Read More" link below for the
dough recipe and information on shaping and baking Frog
Bread.
The Dough
Below if the dough I used, but there
is nothing special about it. If you have a bread recipe your prefer
that produces a sturdy dough, by all means, use
it.
6
cups unbleached flour
2 teaspoons salt
2 teaspoons yeast
1/4 cup sugar
2 cups lukewarm milk
1/4 - 1/2 cup water
Mix
together all of the dry ingredients. Mix in the milk and enough
water to make everything form a doughy ball. Turn the ball out onto
a flat surface and knead for approximately 10 minutes. Return it
into a greased bowl, cover with plastic wrap, and let rise for
approximately 90 minutes until the dough has doubled in
size.
Shaping the Frog

I
first took a large chunk of the dough and formed it into a ball. I
then squished one end of it to make it a bit oblong. This formed
the body of the frog.

Next we added the legs. I made a
smaller ball of dough, cut it in half, and set each half behind the
toad to form the rear legs. I made a small disc of dough and cut it
in half and cut out some toe wedges to form the rear feet. Front
feet, as you can see, were just little tubes of dough that we slit
to create toes.

Eyes are just two small balls of
dough. We pushed a couple of raisins into them to make them "googly
eyes" at our son's request.

A
slit across the front makes the mouth.

All
set. I covered it loosely with a towel and let it rise for an
hour.
Baking
After an hour I preheated the oven to
350. Right before throwing the frog in the oven I coated it with an
egg wash. This was just a raw egg I scrambled up and then brushed
over the dough. Doing this gives the finished bread a beautiful,
shiny coating.
I
baked it at 350 for 45 minutes.
Finished Product

It
came out looking great I think. Our two year old son loved getting
to eat a frog eyeball after dinner, and he is dying to have "frog
butt toast" for breakfast.

All About Frogs
Jim Arnosky
  
When my husband saw this book with the same title as my site at the
library, he simply had to pick it up for me to review. It
turns out, not only is it a great book, my three year old son was
also really into it.
A
couple of minor quibbles:
The
book seems to have some generalizations that seem to miss a few
facts here and there-
For example, the book refers to frogs and toads as "similar but
different animals" - Perhaps it's a linguistics difference, but the
term frog is used to cover the general class of species of
amphibians in the Order Anura (see the
animal kingdom tree here
),
so when folks talk about "frogs" it's generally accepted that they
are talking about frogs and toads - all toads are frogs, but
true toads refers to a specific family in the order
Anura.
Another minor generalization "Only male frogs
make sounds" is also not true for all species, though indeed, for a
large majority of them and for the most common ones this tends to
be the case.
That said, with over 36,000 species, for all
intents and purposes this book pretty well covers all the basics,
and these are merely nits.
Overall though, this was a really great and
surprisingly detailed and comprehensive introduction to frogs, with
some nice drawings. I even found myself learning some new things,
after so many years of running this website!

David Badger
  
Hallelujah! I've found a great coffee table book
about frogs! By this I mean one of those books that has lots of
really beautiful photos of frogs as well as some info about them
that goes beyond just how to feed them bugs (Like the great
articles you run across in National Geographics once every few
years.)
To my knowledge this is the best available book in print.
You can even buy sets of postcards of the photos found in this
book..which I always had lining my drab gray cube walls at
work. |

Reptiles, Amphibians, and
Invertebrates
An Identification and Care Guide Patricia P. Bartlett,
Richard D. Bartlett, Billy Griswold, R.D. Bartlett
  
One of the questions I get all the time is queries from people who
want to identify some frog that they bought at a pet store. Often
frogs are mislabeled, often pet shop owners are just as baffled by
a shipment as the shoppers. This book is a pictorial identification
guide and basic husbandry manual covering more than 250 species,
subspecies, and color morphs of reptiles, amphibians, and
invertebrates, all of which are species most commonly found in pet
stores. |

Frogs
Inside Their Remarkable World Ellin Beltz
  
Herpetologist Ellin Beltz offers a compelling picture of the
history of the frog, its anatomical makeup, its place in the
natural world and the threats that are seriously reducing its
numbers around the world.
This book is simply *brimming* with gorgeous full-color panels
loaded with tons of beautiful photographs and a whole bunch of
information to go along with it. Inside there's a comprehensive
overview, everything you could want to know about frogs - be it
natural history, anatomy and physiology, all the frog families and
the various protective strategies that they take on in the wild.
There's even a whole section dealing with frogs as they relate to
humans, both as they appear in various myths and cultures around
the world. Everything from Aztec beliefs to Kermit the frog, it's
in there. Bonus: This book is so lovely, it's going right on the
coffee table! |

Hopping Mad

Fred lived next door to Finn. Fred had 5 frogs, and so did Finn.
But when the frogs hop over to each other's pads for nighttime
parties and don't all return the next morning, Fred and Finn set
out to build enormous barriers between their houses to keep their
frogs from going next door. What follows is a little mathematical
journey of counting fun as frogs clamor and climb their ways to
night time frolicking.
My four year old son absolutely loves this book, and doesn't even
realize that he's learning lots of math in the
process! |

Care and Breeding of Popular Tree
Frogs
A Practical Manual for the Serious Hobbyist (General Care and
Maintenance of Series) Philippe de Vosjoli, Robert
Mailloux, Drew Ready
  
I got this one at a Reptile and Amphibian show...it looks like a
good resource for anyone planning on owning any tree frogs. The
descriptions of care are very clear, and it even deals with
diseases and disorders that your frog may encounter.
Written by experienced and recognized frog herpetoculturists, this
book covers the most necessary basics - everything from how to
select a healthy animal, how to diagnose and treat an ill one, how
to set up a frog's vivarium, what to feed, and how to breed the
frogs.
It is written for a beginner frog keeper and focuses on species
specifically recommended to beginners - green tree frogs, White's
tree frogs, white-lipped tree frogs, and red-eyed tree frogs.
I don't have one of the popular tree-frogs at home, but this book
has been highly recommended from others who do and it has a lot of
pictures and information that looks like it's a great resource for
the new tree-frog pet owner. |

The Calls of Frogs and
Toads
Lang Elliott
  
This book and CD combo gives an excellent introduction to the
sounds of frog species living in eastern and central North America.
Anyone interested in frogs who spends a lot of time outdoors
listening for them would appreciate this one - you'll be able to
not only tell which frog you're hearing but what they are saying
too! It starts out with all the species calls, and then theres a
whole section on the CD with narrated explanations and examples of
various types of calls, like advertisement calls (HEY,
Baby!), aggressive calls, release calls, rain calls, distress
calls, warning calls, mixed species choruses and so on.
Back when I got a copy, the CD didn't come with a full book like it
does now - which appears to have some added information and
pictures... just to make it that much more
interesting.
Note: If you are on the west coast like me,
this book will be lacking a bunch of species that are common here.
So this is best used as a reference guide for those in the middle
and eastern parts of the country.

Days with Frog and
Toad
Arnold Lobel
  
These Frog and Toad stories are wonderfully written tales about the
rewards of good friendship. Our son really loves this series, and
we don't grow tired of rereading this one to him on a nightly
basis. |

Frog and Toad Are
Friends
Arnold Lobel
  
This one is currently my 3 year old son's favorite book. I don't
think we've gone by a single night in the past 6 weeks where a
story hasn't been read from our copy. Frog and Toad are best
friends and this series is about their time together. There are 4
cute little stories to be enjoyed in this book. |

Breeding and Keeping Frogs and
Toads
(Completely Illustrated with Color Photos Showing Breeding and
Keeping) W.P. Mara
  
This one is probably my favorite general pet care book. It's full
of really great pictures and has glossy pages (presumably because
your handling wet frogs?) and has some very clear basic
descriptions of frog care.
Probably the most exhaustive section on Frog Illness that I've been
able to find yet. This one ends up being the book I refer to most.
It seems to be a pretty comprehensive resource for the basic
pet-care needs. |

A Boy, a Dog, and a
Frog
Mercer Mayer
  
This is the first book in a series of wordless picture books
following the tale of a boy and his dog who go out exploring and
find a frog. It's a very sweet tale, with really cute and
expressive drawings.
We loved reading this book with our 3 year old as much as he did,
so it's not just for kids too. |
|
One Frog Too Many
Mercer Mayer and Marianna Mayer
  
Oh my goodness what a cute book series this is!
This falls under the wordless picture book genre - a story about a
boy, his dog, turtle and frog, and a case of envy when a new frog
joins the little group. The illustrations are priceless, with
expressions so clear even our young 3 year old has no troubles
figuring out what emotions each character is expressing.
This one is just as delightful the 100th time as the first time,
for the young and old alike. |

Frog Heaven
Nature's Song
  
This is one of my favorites. It's just a steady recording of
various frog calls: makes you feel like you're in a lush forest,
(even if you live in the middle of the city, like me) It's great
background noise and nice to fall asleep to!
This is still one of my all-time favorite nature-recording CDs, of
any genre, and not just because of the froggies! |

Poison Dart Frogs
(Success With An Amphibian Pet) William Samples
  
For the hardcore herp fans, this book appears to be one of the best
ones out there when it comes to reference books for poison dart
frog owners. It includes step by step instructions for breeding,
raising eggs, care of tadpoles, food, terrarium, and so on. The
intended audience clearly includes breeders, not just the casual
pet owner, so it may be too technical for beginners. (That said, I
really don't recommend poison dart frogs for "beginners"
anyway.) |

Sounds of North American
Frogs
Smithsonian Folkways
  
The folks out at Smithsonian Folkways have a CD released with some
frog sounds on it. This is a delightful recording, digitally
remastered and narrated by herpetologist Charles M. Bogert, which
is great as a teaching tool for the many many different kinds of
sounds that frogs make! Great way to learn how to frog hunting with
your ears! |

Tuesday
David Wiesner
  
Looking for a great children's book with frogs? Check this one out!
It's by far my favorite and you don't have to be a kid to truly
appreciate it!
Minimal text, beautiful drawings.
This book even won the Caldecott Medal and is practically
guaranteed to charm even those who don't think they really like
frogs. Its a story about a Tuesday evening when Frogs begin a
magical journey of flight. The images here are absolutely priceless
and hysterical! |

Amphibian Medicine and Captive
Husbandry
Kevin M. Wright, Brent R. Whitaker, Kevin N.
Wright
  
If you're even considering this one, chances are there's really
absolutely nothing that *I* can teach you, but I'm going to
list this one in the recommended reading list anyway since this
is, after all, a frog site!
This book comes with high recommendations from aspiring
veterinarians, but any serious herpetologist or serious breeder of
captive amphibians would find information in this book useful. It
covers all sorts of detailed bits about care, feeding and breeding
of amphibians, as well as diagnosis of all sorts of diseases that
they can get as well as methods of treatment. |

Amphibians of Washington and
Oregon
William P. Leonard, Herbert A. Brown, Lawrence L.C.
Jones, Kelly Rorc Allister, and Robert M. Storm (Seattle Audubon
Society)
  
If you live in the Northwest, this is a pretty good field guide for
local "frog watchers." It even has information on how to identify
different kinds of tadpoles. |
|
Frogs, Toads, and
Treefrogs
Everything About Selection, Care, Nutrition, Breeding, and
Behavior R. D. Bartlett, Patricia P. Bartlett
  
A popular soft-cover book that's easy enough for kids to understand
as well. Lots of pictures and a good basic introduction to pet care
information. |
|
Amphibians and Reptiles in
3-D
Mark Blum
  
What a fun book! This one comes with special glasses embedded in
the front. Using these glasses, you can check out really cool
photographs of frogs and other reptiles in 3-D! |

The Frog Prince
(We Both Read) Brothers Grimm, Sindy McKay, George
Ulrich
  
Here is the classic tale of the Frog Prince, a princess makes a
promise to a frog to be his friend, in exchange for his help in
retrieving her golden ball, but it's also a perfect introduction
for young readers.
This book has been designed for kids just starting to learn to read
to share the book with a better reader, by using different levels
of vocabulary. Everytime you turn a page, there's a section on the
left page for the better reader to read aloud, and on the right
there's a bit for the young learner to try out which uses simpler
language.
It's also a nice adaptation of the classic tale. Our son is just
starting to get interested in reading, and though this is a bit
advanced for him, he loved the story here. We'll definitely be
returning to it when he's getting closer to this reading level -
probably 1st grade. Plus it's just lots of fun to read together at
bedtime! |

It's a Frog's
Life!
Densey Clyne
  
Great photos and a really great intro to frogs for the
beginner. |

The Book of the
Toad
A Natural and Magical History of Toad - Human Relations
Robert M. Degraaf
  
An awesome historical look at the perception of Toads throughout
history! I learned all kinds of neat stuff about toad myths and
medicine. There's even a section dealing with famous artworks, from
ancient Chinese sculptures, to eerie paintings of
Bosch! |
|
The Wide-Mouthed
Frog
A Pop-up Book Keith Faulkner
  
Another favorite book around here. It's especially fun when you
making all the funny voices when reading this one
aloud! |

Froggy Gets
Dressed
Jonathan London
  
This was one of my sons absolute favorite books when he was 2-3
years old. I read it to him countless times and yet it's always a
pleasure to read.
Froggy wakes up in the middle of winter and insists he wants to go
out to play, but he keeps forgetting to finish getting dressed
before flopping out into the snow (flop flop flop).
They have this one in board-book too! |

Frog Pond
Recordings and Sounds of Frogs CD Natures Music
  
Three recordings on this album: Frogs and Stream, Frogs in Summer,
and Frogs and Rain. It's an hour or so of audio recordings of
ambient frog pond sounds. |
|
The Nature of
Frogs
Amphibians with Attitude Harry Parsons
  
Lots of great frog images, and there's a lot of "dinner
conversation" style information about frogs in here too - things
like the myths about frogs in history and so on. A nice addition to
a frog enthusiast's book collection. |
|
Poison Frogs of the Family
Dendrobatidae
Jewels of the Rainfores Jerry J. Walls
  
The pictures in this book are fabulous. This oversized book is rich
with color glossy photographs of the most amazing amphibians on
earth. As a pet care book, I understand the book is lacking in some
technical detail that will have serious herp-breeders frustrated,
but as a coffee table book full of glorious images this book really
fits the bill. As a pet care manual, skip this one and save your
money. |

Frogs & Toads As A New
Pet
A Complete Introduction John Coborn
  
Good basic introduction for the beginner frog owner. This has most
of what you need to know, including some good photos, a section on
setting up housing, some basic health care...that sort of
thing. |
|
The Proper Care of
Amphibians
John Coborn
  
Another slightly heftier book compared to his other title, it also
has some info on salamanders and newts. Thick pocket book with
lots-o-info and pictures. |
|
Amazing Frogs and
Toads
Eyewitness Juniors A Dorling Kindersley Book
  
Basically full of the same info as the bigger Eyewitness book, but
less photography and more drawings. Though it's a smaller book it's
still a great resource! |
|
Echoes of Nature
Frog Chorus Echoes Of Nature (Laserlight Series)
  
A bunch of frog recordings taken from various places in the field.
One complaint I have heard about this one is that it sounds like
it's a bit uneven - so if you're looking for purely atmospheric it
might not fit the bill, and yet there's not accompanying narration
so it's not instructional either. However, it's definitely got some
variety of frog calls here. |

The Strange Story of the Frog Who Became a
Prince
Elinor Landor Horwitz (Illustrations by John
Heinly)
  
I loved this book when I was probably about 8 or so. The very idea
is fabulous...a witch comes along and turns a frog into a prince,
who wants nothing more than to go back to being a
frog. |
|
Keeping and Breeding
Amphibians
Chris Mattison
  
Bigger sized more general info, this deals more with different
species of frogs rather than health guides. The illness section is
only about two pages, but it offers a lot in the way of good
information on each species of frog. It also deals with both frogs
and other amphibians such as salamanders and
newts. |

Frogs and Toads
A Sierra Club Book for children Steve Parker
  
Great artwork and descriptions. Lots of weird frog fact info here
for all ages. |

Breeding Food Animals Live
Food for Vivarium Animals
63 Black-and White photographs and drawings Ursula
Friederich, Werner Volland
This book talks about the basics of breeding animals to feed the
growing number of fish, reptiles, amphibians, predatory insects,
and birds being kept as pets. This actually isn't specifically
about frogs, but since many frogs eat more than just bugs, and in
fact eat things like mice and so on, this book seemed relevant and
worthwhile to list. If you want to look into breeding your own
feeder animals to fix breakfast for your favorite croaker, this
book is an excellent resource. |
The Frog and the
Crocodile
Once, there was a frog who lived in the
middle of a swamp. His entire family had lived in that swamp for
generations, but this particular frog decided that he had
had quite enough wetness to last him a lifetime. He decided that he
was going to find a dry place to live instead.
The only thing that separated him from dry
land was a swampy, muddy, swiftly flowing river. But the river was
home to all sorts of slippery, slittering snakes that loved nothing
better than a good, plump frog for dinner, so Frog didn't dare try
to swim across.
So
for many days, the frog stayed put, hopping along the bank, trying
to think of a way to get across.
The snakes hissed and jeered at him, daring
him to come closer, but he refused. Occasionally they would slither
closer, jaws open to attack, but the frog always leaped out of the
way. But no matter how far upstream he searched or how far
downstream, the frog wasn't able to find a way across the
water.
He
had felt certain that there would be a bridge, or a place where the
banks came together, yet all he found was more reeds and water.
After a while, even the snakes stopped teasing him and went off in
search of easier prey.
The frog sighed in frustration and sat to
sulk in the rushes. Suddenly, he spotted two big eyes staring at
him from the water. The giant log-shaped animal opened its mouth
and asked him, "What are you doing, Frog? Surely there are enough
flies right there for a meal."
The frog croaked in surprise and leaped away
from the crocodile. That creature could swallow him whole in a
moment without thinking about it! Once he was a satisfied that he
was a safe distance away, he answered. "I'm tired of living in
swampy waters, and I want to travel to the other side of the river.
But if I swim across, the snakes will eat me."
The crocodile harrumphed in agreement and
sat, thinking, for a while. "Well, if you're afraid of the snakes,
I could give you a ride across," he suggested.
"Oh no, I don't think so," Frog answered
quickly. "You'd eat me on the way over, or go underwater so the
snakes could get me!"
"Now why would I let the snakes get you? I
think they're a terrible nuisance with all their hissing and
slithering! The river would be much better off without them
altogether! Anyway, if you're so worried that I might eat you, you
can ride on my tail."
The frog considered his offer. He did want to
get to dry ground very badly, and there didn't seem to be any other
way across the river. He looked at the crocodile from his short,
squat buggy eyes and wondered about the crocodile's motives. But if
he rode on the tail, the croc couldn't eat him anyway. And he was
right about the snakes--no self-respecting crocodile would give a
meal to the snakes.
"Okay, it sounds like a good plan to me. Turn
around so I can hop on your tail."
The crocodile flopped his tail into the
marshy mud and let the frog climb on, then he waddled out to the
river. But he couldn't stick his tail into the water as a rudder
because the frog was on it -- and if he put his tail in the water,
the snakes would eat the frog. They clumsily floated downstream for
a ways, until the crocodile said, "Hop onto my back so I can steer
straight with my tail." The frog moved, and the journey smoothed
out.
From where he was sitting, the frog couldn't
see much except the back of Crocodile's head. "Why don't you hop up
on my head so you can see everything around us?" Crocodile
invited.
"But I don't want to see anything else," the
frog answered, suddenly feeling nervous.
"Oh, come now. It's a beautiful view! Surely
you don't think that I'm going to eat you after we're halfway
across. My home is in the marsh-- what would be the point of
swimming across the river full of snakes if I didn't leave you on
the other bank?"
Frog was curious about what the river
looked like, so he climbed on top of Crocodile's head. The river
looked almost pretty from this view. He watched dragonflies darting
over the water and smiled in anticipation as he saw firm ground
beyond the cattails. When the crocodile got close enough, the frog
would leap off his head towards freedom. He wouldn't give the croc
a chance to eat him.
"My nose tickles," the crocodile complained
suddenly, breaking into the frog's train of thought. "I think there
might be a fly buzzing around it somewhere, or a piece of cattail
fluff swept into it while I was taking you across the
river."
"I
don't see a fly," the frog said, peering at the crocodile's green
snout. It seemed odd that anything could tickle a crocodile through
it's thick skin.
"Would you go check my nose for a piece of
cattail fluff, then?" the crocodile begged, twitching his nose.
"I'm afraid I'll sneeze and send you flying. I don't want to feed
you to the snakes." A tear seeped out of his eye, as if he was
holding back a mighty sneeze.
The bank isn't too far, the
frog thought. And it's the least he could do to repay him for
bringing him over. So he hopped onto the crocodile's snout and
checked the nostrils. Just a little closer, and he could jump... "I
don't see--" he began.
Just then, with a terrific CHOMP! the frog
disappeared. The crocodile licked his lips in satisfaction and gave
a tiny half-sneeze. "Good, I feel much better already," he smiled,
and turned around to go back home.
Frogspawn, tadpoles and frogs
(Frequently asked questions)
When do frogs lay
frogspawn?
Frogs return to ponds each February
or March to lay their frogspawn and then most of them disappear,
just as quickly as they arrive! The timing depends on the weather
and your actual location. Where we live 'Up North' it will be later
than for those who live in warmer climes!
Do frogs live in a
pond?
Frogs spend the majority of their
time on dry land, under stones or in a damp cool spot in your
garden. They use ponds at spawning time to lay their frogspawn, but
need to be on land to feed. If the frogs cannot escape because your
pond has steep sides and a low water level, or pavings that
overhang into the pond then they will die. You must make
provision for them to escape. How? See the next
question!
How do I make a 'ladder' for
my frogs and other wildlife to get out of the
pond?
Sometimes there may be natural plants
at the pond edge that frogs can use to gain a foothold. Floating a
piece of wood on the pond surface and securing the outer end is
another option. If this isn't possible, consider making a
‘ladder’, from plastic mesh, such as clematis mesh.
Make sure the mesh extends below the water line. The top end can
then be easily pinned to the surrounding soil or grass that’s
round your pond. If your pond is edged with stone then the mesh
could be held in place with a flat stone placed on top of the
original. This technique also helps hedgehogs to escape. Hedgehogs
are particularly 'accident prone' and often drown in garden
ponds.
I have been given some
frogspawn. How do I ensure its
development?
Frogs lay frogspawn at an optimum
depth, which is always in the shallow sections of a pond. Try to
emulate this, and put stones in some sections if necessary to
reduce the depth of water, thus enabling the frogspawn to either
float on, or just below the surface. Wildlife ponds should always
be built with ledges and varying depths to allow for this. See
the
Get
Digging page. If the water is too deep, or
the frogspawn is not lowered carefully into the pond, it may well
sink to the bottom of the pond where it will die. Try to avoid
having large areas of paving round the pond as these are not
‘frog friendly’ and can cause frogs to stick to them in
hot weather. The frogs then dehydrate and die. Frogs prefer cool
and damp surroundings. If you let grass and plants extend to the
edge of the pond this would give tiny froglets a ‘half
way’ house when they exit the pond. Tall plants round your
pond edges will also discourage herons from wading into your pond
to catch your frogs.
Will my goldfish eat my
frogspawn and tadpoles?
In a word - Yes! Goldfish are
carnivorous and will also eat newts eggs, dragonfly larvae and
anything else that moves!
One site visitor reported -
'Several years ago I put all the spawn in
a tank and it all hatched.... when I thought they were large enough
I put them in the pond and the fish ate the lot!' but
another found that ' ... the fish live very
well alongside the frogs and we found numerous little frogs under
stones we have aside a 'stream'. Last year the tadpoles hid from
the fish in the pebbles we have in the pond.' So ...
providing hiding places for the tadpoles might well be an
acceptable compromise.
Why is my frogspawn a milky
colour?
It's most probable that cold weather
has caused this effect, and the frogspawn will probably not develop
into tadpoles. Other hatched tadpoles will eat the jelly though, so
nothing is wasted! See also the
RAUK e-forum
for 'white
frogspawn'
What do tadpoles
eat?
Tadpoles will live on the jelly that
provided protection before they hatched, and will survive on algae,
other microscopic particles and vegetation in the pond. Once they
start to develop legs, tadpoles change from being vegetarian
creatures to a carnivorous stage. Most established ponds will have
enough food for the tadpoles to develop to maturity, but if the
tadpoles or developing froglets are in a tank they may well start
eating each other if food is scarce. Not a pretty sight! Our mature
tadpoles were given a treat of small quantities of cat food and the
small cat biscuits that floated on the water. They relished both.
Remember to keep the quantities small though to avoid polluting the
pond water.
I have found dead frogs in my
garden. What would cause this?
(1) The frogs might have been
attacked by neighbouring cats. (2) Some frogs die at spawning time
after becoming entangled with other enthusiastic frogs. (3) Your
frogs could be suffering from a frog virus. Scientists think that
the virus might have been imported by exotic pets and have
investigated 62,000 frog deaths, but believe the actual toll runs
into millions. 'It's worse than myxomatosis, the plague that
devastated rabbit populations,' said Tom Langton, director of
research group Froglife. 'It is a living death. The frogs take a
considerable time to die and there are some indications that their
numbers are permanently depressed in some areas.' The disease was
first reported in southern England in 1992. Since then, increasing
numbers of frogs suffering from the disease have been found further
north, in Cheshire and Scotland. Anyone who finds dead or dying
frogs should contact Froglife on 01733 558960.
Where do the frogs go in
winter?
After spawning, most frogs will
return to dry land and return to your pond later in the summer, to
either bask in the shade around the pond, or cool off in the water.
By late summer they'll have gone again. Some will hibernate in dry
stone walls, under stones etc. whilst others will stay at the
bottom of a pond in an attempt to be the first to attract females
the following spring. When I had to make urgent repairs to our pond
in January (the liner had been punctured by herons) I discovered 55
frogs hibernating in the mud. These were temporarily transferred to
our other pond and came to no harm. Both ponds are very small but
support a diverse range of wildlife, so don't be deterred if your
garden and the pond you build are only small.
How do I get rid of all the
extra frogspawn in my pond?
Frogs lay so much frogspawn because
only a small percentage of it will ever develop into tiny froglets.
Fish will eat frogspawn and tadpoles, and so will birds and many
other pond predators. Once the frogspawn has developed into
tadpoles, it will not look anywhere near as much, so I would leave
it where it is. Frogs are the gardener's friend and, for many
children, watching tadpoles is a fascinating experience. Many
natural ponds have been destroyed to make way for new housing and
businesses, so anything you can do to encourage frogs to your
garden will be beneficial to the development of the species. Also,
see the question below.
How can I stop frogs laying
frogspawn in my pond?
This is a wildlife preservation web
site! Frogs are to ponds what plants are to gardens or birds are to
trees. It's natural that frogs will lay frogspawn in your garden
pond. Frogs are such placid creatures. In summer they will sit
either in or around your pond and will create a soothing ambience
as they nonchalantly watch the world go by! Frogs cause no harm to
anyone or anything, (apart from garden pests). If you have a real
aversion to frogs, either fill in the pond, or permanently cover it
with a fine netting for the entire year. Be aware that you will
also then restrict all other wildlife from visiting your pond. Also
remember that birds and other animals can become entangled in pond
netting, causing them severe injuries, or even
death.

Three weeks after being laid
the frogspawn is starting to develop into tadpoles. Although it may
not be obvious in this small picture, the black dot inside the
frogspawn jelly is now elongating into a tadpole shape. The weather
in this part of Lancashire is often cold, and some mornings
recently the pond has been frozen. Cold weather can cause the
frogspawn to go milky white and kill it. See the
FAQ
page.
|
 |
| |
|
 |
At four weeks there is a
definite tadpole shape now, but the cold spring is hampering
development. Some web sites claim that frogspawn takes only 10 days
to develop into tadpoles. Not in the North West of England, it
doesn't, and particularly if your garden is like ours and is more
than 800 feet above sea level.
|
|
Now five weeks old and much of
the frogspawn now looks like miniature eels, clearly visible on top
of the jelly. This the next development stage, the change into true
tadpoles, complete with wiggling tail, and yes, it's still
cold!
Update - The following year the warm weather meant that the
tadpoles reached this stage a full two weeks earlier than in the
previous year.
|

|
 |
It's now seven weeks since the
frogspawn was laid and we have thousands of 'proper' tadpoles. If
only a small proportion of them develop into adult frogs, the slugs
had better watch out!
Update - Although the weather is warmer, and the tadpoles
hatched earlier, this year's tadpoles are at this stage. Nature
seems to have a way of evening things out.
|
15th June - Disaster strikes!
A 'flash flood' (the heaviest sustained spell of rain in the area
for 20 years - and it rains a lot in Lancashire!) caused the pond
to overflow into the surrounding garden with the loss of many
tadpoles who seemed intent on making a bid for freedom instead of
staying in the deep water of the pond. I scooped up as many as I
could with a tablespoon! I also cleaned the pump filter and found
that many had sneaked through the thin plastic grille of the pump
housing and died. No wonder frogs lay so much frogspawn. I have
replaced the pump's inbuilt sponge filter with a
Rotorflush external
filter.
This has a fine wire mesh to avoid a recurrence and minimizes pump
maintenance. I have also installed a controlled overflow pipe to
the pond. This is fitted with a fine gauze to prevent siphoning out
the tadpoles as well and it should cope with future storms.
14th June (the following year) Ironically, almost
a year to the day we had another 'flash flood'. This time there was
no scooping up of tadpoles from the garden, so the controlled
overflow system was obviously effective. The tadpoles are still
small; not even any legs yet. The weather has been terrible for the
whole of May and the first half of June. Rain almost every day,
overcast skies and consequently no sun to warm the water in the
pond.
28th July Tiny
froglets were seen in and around the pond. The frogspawn was laid
on 4th March, so it has taken a long time to get to this stage,
certainly much longer then the text books say!

About Frogs
Tongues
Back to front- a frog's tongue is
fastened in the front, not the back and is folded backward to the
throat. It shoots out with a speed truly beautiful to behold, hits
the fly, and zips in. And of course, in the cartoons, they do more
than can be done in real life. A frog does not aim well after
shooting the tongue out, nor will it change direction midstream.
Many need to move their whole heads, not just shoot a tongue behind
their heads like a cartoon.
The tongue of a frog is about a third
of the frog's length. Sounds impressive, until you realize if a
human had a comparable tongue, it would reach a bellybutton. Seems
far for a human, but not a frog. The tongue can flip back in 15/100
of a second, though, which is faster than human can follow. Despite
this, I swear some humans talk almost as fast as that frog's
tongue. Maybe frogs are more like us than we care to
admit.
Using a test call synchronized
electromyography, experts have recently discovered new ways the
frog's tongue works. The muscles start are loose and mushy, and
when ready, some become rigid, like a rod down the middle of the
tongue, and a second group of muscles, perpendicular to the base of
the tongue, stiffen. This shoots the tongue up. Think a wet towel
snapping, or a whip.
Other muscles pull the tongue back
in. The test basically connected tiny little wires to the frog
tongue, and measured current. Using high speed photography also
helped to show which muscles did which work. Good jumpers, good
aim, the inspiration for Kermit the frog- these amazing creatures
have amazing tongues and continue to astound us.
The frog has a sticky tongue that
folds backwards, toward its throat. The frog can whip this sticky
muscle out of its mouth, snap up a fly and gulp it down before the
fly even knows it isn't flying anymore.
How does this amphibian get that
tongue out there so fast? The tongue is attached to the front of
the mouth, instead of the back. This means the tongue's anchor, and
so strength, lies at the front of the frog's mouth, not the back.
This allows the frog to catapult his tongue outward, much as a
human would use his wrist, not his shoulder, to snap a
whip.
The stickiness of the frog's tongue
means that fly is stuck on there. Frogs also like worms, and bugs
in general. Since the frog doesn't have fingers and so can't pick
up his meals, the anatomy of his tongue proves very
useful.
Unfortunately, a frog's tongue
doesn't do much for him when a snake decides to make a snack of
him.
Have you ever seen a frog catch a
fly? It flicks its tongue out and at high speed like the crack of a
whip, the fly appears to have disappeared and the frog appears to
be swallowing. Don't blink or you'll miss it.
So how does its tongue flick out that
far? How does the frog keep it in its mouth? What is the anatomy of
a frog's tongue?
The frog tucks its tongue down it's throat, where else can he put
it; his tongue is so long that its the only logical place it can
go, it has evolved this way; evolution is always logical. Its
tongue is attached to the front of the mouth for a vital few
centimetres of extra length and to increase the speed of
deployment.
A tongue of any animal is made of
pure muscle; it has unsurpassed strength and solidity which is
perfect for the frog that needs a rapid action to catch an elusive
fly.
Once he has made contact with the
fly, he needs a good grip to hold on and pull it back into his
mouth and so the frog has evolved to have extremely sticky mucus on
its tongue, which sounds disgusting but is amazingly
effective.
However next time you think about
kissing a frog, I would avoid using your tongue.
Sometimes humans tongues are long
enough to touch the tip of their nose, but most of us only have a
couple inches of tongue that can stick out of our mouth. Imagine
having a tongue that is so long, it can reach out and catch
something several inches away! This would be cool if you were a
frog. Frog tongues are attached in the front in stead of the back
like ours. They fold back and wait for 'supper' to fly by. Once the
frog spots it's dinner, the tongue can flick out rapidly, catch
dinner with it's sticky mucus, and reel it back in. Then it has
small 'teeth' in it's upper mouth that aren't very good for biting,
but they help hold the food and break it up a little big. The frogs
mouth is where digestion begins, just like for humans, but that's
where the resemblance ends. A frog's tongue is very specialized to
help him catch his food. He uses his tongue like you would a
fishing pole, casting it out, 'hooking' his prey, then reeling it
in. Yum!
The tongue of a frog is slightly
forked but not to the same degree as a snake. The tongue is
slightly sticky to assist it in the catching of its food, flies,
worms and other insects.
When inside its mouth the tongue sits
in a partial curl but more of a folded type position, contrary to
the popular belief that it is curled like a roll of
carpet.
From the folded position the frog
throws its sticky tongue at its prey, much in the same way you
would cast a fishing line. Its hunting is much like our fishing
because like us the frog then has to reel its tongue back, drawing
the similarity to fishing.
The frogs tongue is different to ours
because of several points:
1 - Proportionally much
longer.
2 - Slightly
sticky.
3 - Has a slight forking to the end
of it.
4 - It sits in a curled position when
inside the mouth.
5 - The tongue in attached at the
front of the mouth instead of the rear.
