Reptiles are vertebrates, they have scaly skin that keeps their bodies from drying out, and their young do not go through a larva stage like amphibians but instead look like small versions of the adults when they emerge. Reptiles are ectotherms, so they must bask in the sun or find a warm spot to get warm and become active, and they must find shade or a cool spot to cool off. In cold conditions they become sluggish and don’t move around much, and some enter a state of torpor or hibernation if it will be cold for a long time.
Females migrate en masse to egg-laying sites. Dig elaborate burrows with labyrinthine tunnels. Egg laying takes place in February or March. 25 to 40 eggs are buried 12 inches deep in moist sand or soil.
