Comments: Rivers, ponds, lakes, canals, large springs with overhanging foliage, marshes; all types of freshwater habitats in Florida. Sometimes in brackish water at stream mouths. Basks on sand bars and fallen logs. Often burrows into sand-mud bottom, leaving only head out. Eggs are laid in sandy, sunny areas near water. In Florida, a nest was in the sand apron of a recently abandoned gopher tortoise burrow, 103 m from the nearest body of water (Heinrich and Richardson, 1993, Herpetol. Rev. 24:31).
