Reptiles and Amphibians are ectothermic animals. This means they rely on their environment to regulate their internal body temperature. They achieve this by either basking in the sun or seeking shade. These cold-blooded animals need much less foot than their warm blooded counterparts. Amphibians were among the first vertebrate animals to live on land, however they are bound to fresh water. Reptiles do not need to absorb water. Reptile fossil remains are found on every continent.
