Gopherus polyphemus
The gopher tortoise is a moderate-sized, terrestrial turtle, averaging 23–28 cm (9–11 in) in length. The species is identified by its stumpy, elephantine hind feet and flattened, shovel-like forelimbs adapted for digging. The shell is oblong and generally tan, brown, or gray in coloration. Gopher tortoises can live 40 to 60 years in the wild. Gopher tortoises are ancient: their ancestors are a species of land tortoise that originated in western North America some 60 million years ago. They are members of the Class Reptilia, Order Testudines, and Family Testudinidae. Of five North American tortoise species (genusGopherus), the gopher tortoise is the only one that occurs east of the Mississippi River. http://myfwc.com/wildlifehabitats/profil...
Gopher tortoises live in well-drained sandy areas with a sparse tree canopy and abundant low growing vegetation. They are commonly found in habitats such as sandhill, pine flatwoods, scrub, scrubby flatwoods, dry prairies, xeric hammock, pine-mixed hardwoods, and coastal dunes which have historically been maintained by periodic wild fires. When fire is suppressed in gopher tortoise habitat, small trees, shrubs, and brambles begin to grow making it difficult for the gopher tortoise to move around and eventually shade out the low growing plants that gopher tortoises eat. During winter, tortoises are much less active; although on warm afternoons some individuals trudge to the earth's surface to bask on the sandy aprons of their burrows. A superb earth-mover, it lives in long burrows that offer refuge from cold, heat, drought, forest fires and predators. The record length for a burrow is over 47 feet long, however, the burrows average 15 feet long and 6.5 feet deep. The burrows maintain a fairly constant temperature and humidity throughout the year and protect the gopher tortoise and other species from heat, cold, drought, and predators. Burrows also act as a refuge from the periodic, regenerative fires that are required to maintain the quality of their habitat. Gopher tortoises have adapted to living in dry habitats with frequent fire occurrence by digging burrows deep into the sandy soil. The absence of natural cycles of burning in pine forests spells hardship for tortoises. The dense vegetation (shrubs, brambles, small trees) that grows in a forest in the absence of fire shades out the tender herbs tortoises like to eat, and limits their food supplies. Fire is vital in maintaining many native ecosystems, like longleaf pine sandhills, where gophers live. http://myfwc.com/wildlifehabitats/profil...
