Herpetology

... part of their life, if only the laying of eggs or birth of young. Their skins have many glands and are often toxic. Reptiles, by contrast, have a dry watertight skin, usually protected by scales , that normally has few if any glands. The reptilian heart is a three-chambered one (four-chambered in ...
