Reptile Discovery

Reptiles are cold-blooded or ectothermic, which means they cannot regulate body temperature on their own and the main reason why reptiles are different from mammals and birds. Because they rely on their environment to keep warm, you see them basking in the sun, and to avoid overheating, they seek shelter to avoid absorbing too much heat.

Reptiles are found on every continent, except Antarctica, and have existed for more than 300 million years.

CONSERVATION STATUS: Varies depending on the species.
