Osceola Forest Wildlife "Eastern Indigo Snake" Mystery Cache

The Eastern indigo snake is a non-venomous, bluish-black colored snake that can reach lengths of eight feet (2.4 meters).  Its chin, cheek, and throat are mostly red or brown, but can also be white or black.  Most indigo snakes have smooth scales, although adults do have keels (ridges) on the front of some of their scales (Florida Natural Areas Inventory 2001).  When approached, the Eastern indigo snake shows no aggression They are also exothermic species – their body temperature is externally regulated.

Life History

The Eastern indigo snake’s diet primarily consists of a variety of species, including small mammals, birds, toads, frogs, turtles and their eggs, lizards, and small alligators (National Park Service, n.d.). 

Indigo snakes begin breeding between the months of November and April and nest between the months of May and August.  Females lay 4-12 eggs yearly or bi-yearly, with the eggs hatching 90 days after being laid.  Since the indigo snake is a commensal of the gopher tortoise, females usually deposit their eggs in gopher tortoise burrows.  Females may have the ability to hold sperm, which would allow them to defer fertilization of an egg.  Parthenogenesis (a form of asexual reproduction) may also be possible with Eastern indigo snakes, as some virginal snakes have been seen laying eggs . 

Habitat and Distribution

Eastern indigo snakes inhabit pine flatwoods, hardwood forests, moist hammocks, and areas that surround cypress swamps.  They can be found throughout Peninsular Florida and southeastern Georgia (Florida Museum of Natural History, n.d.).

Threats:

The main threats facing the Eastern indigo snake is habitat destruction, fragmentation, and degradation.  Habitat destruction is caused mainly by the extension of urban development in their habitat.  Indigo snakes lose more than 5% of their habitat each year in Florida .  As a species that often occupies gopher tortoise burrows, indigo snakes face being injured by people hunting for rattlesnakes in the burrows.  This action usually causes death to other species in the burrow including Easter indigo snakes.  Habitat degradation is also a result from this action.  Habitat fragmentation is also a threat as increased housing and road development can separate their habitat into smaller individual habitats.  Small fragmented habitats can have problems supporting a viable population.  Other threats include pollutants, vehicle strikes, captures for domestication, and intentional killings.
