List of reptiles

Reptiles are interesting four-legged animals that belong to the class Reptilia. They include groups like turtles, crocodilians, snakes, amphisbaenians, lizards, and the tuatara, along with animals that lived long ago. The study of these animals and amphibians is called herpetology.

This list of reptiles groups these amazing animals by family and includes two smaller groups. In this list, the word "reptile" is used in its common way, which is not a complete group of animals. This means it does not include birds. While birds are scientifically a type of reptile, they are not on this list.
