List of reptiles
Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The following list of reptiles lists the vertebrate class of reptiles by family, spanning two subclasses. "Reptile" here is taken in its traditional (paraphyletic) sense, and thus birds are not included (although birds are considered reptiles in the cladistic sense). Subclass Diapsida. Division Archosauria. Superorder Crocodylomorpha
