What is a Reptile?
|
|
Reptiles include snakes, lizards, crocodilians, and turtles. Reptiles are cold-blooded. (They depend upon their environment to provide warmth.) Most reptiles are egg-layers, although some produce live young. In cold regions, reptiles hibernate. In extremely hot or dry climates, some reptiles will estivate, or go into a torpor. Because they lack internal heating mechanisms, reptiles depend on external heat sources. Thus, you will often find them lying in the sun on rocks and logs. Most reptiles have a three-chambered heart. |
