Welcome to Shark Week!! Every year since 1988, the Discovery Channel has devoted a week each summer to sharks. What started as an attempt to educate the public that there was more to sharks than just what they saw in Jaws has since become a cultural phenomenon. Last year while watching Shark Week, EmmaBoo227 started to write the names of sharks on log sheets she created and stuck them in a handful of containers we had won at a raffle and the idea for a shark week series was born.
But where to hide a shark week series? In the ocean would be ideal, but not realistic. But we have a body of water nearby. And while the caches can’t really be hidden in the lake, we could make them all puzzles and hide the caches around the lake. So that’s what we did. We hope you enjoy learning a little about some sharks you have probably heard of and learning a little more about some sharks you have probably never heard of.
These hides are all placed around Folsom Lake. Care was taken to avoid poison oak as much as possible, but it is still out there. Also beware off all the other hazards of the lake including, but not limited to, ticks, snakes, other animals, heat and uneven footing.
Cache is located at N38 43.FAD W121 06.CBE
Kitefin Shark
The kitefin shark or seal shark (Dalatias licha) is a species of squaliform shark in the family Dalatiidae, and the only species in its genus. It is found sporadically around the world, usually close to the sea floor at depths of 200–600 m (660–1,970 ft). With a sizable oil-filled liver to maintain neutral buoyancy, this shark is able to cruise slowly through the water while expending little energy. The kitefin shark has a slender body with a very short, blunt snout, large eyes, and thick lips. Its teeth are highly differentiated between the upper and lower jaws, with the upper teeth small and narrow and the lower teeth large, triangular, and serrated.
Armed with large teeth and a strong bite, the kitefin shark is a powerful, solitary predator that takes many different types of prey, ranging from bony fishes, sharks and rays, to cephalopods, crustaceans, polychaete worms, siphonophores, and possibly carrion. It also takes bites out of animals larger than itself, similar to its smaller relative, the cookiecutter shark (Isistius brasiliensis).
