Reptiles are vertebrates, they have scaly skin that keeps their bodies from drying out and their young do not go through a larva stage like amphibians but instead look like small versions of the adults when they emerge. Reptiles are ectotherms, so they must bask in the sun or find warm spot to get warm and become active and they must find shade or cool spot to cool off. In cold conditions they become sluggish and don’t move a round much and some enter a state of hibernation if it will be cold for a long time.

Some crocodiles and snakes stay to guard the next after laying their eggs and even help the child get started life. The child are independent from start and must find their own food and shelter. Reptiles are born on land and are born with strong instincts, so they are on their own at birth. Unlike birds and mammals reptiles do not maintain a constant internal body temperature without fur or feathers for insulation, they cannot stay warm on a cold day and without sweat glands or the ability to pant, they cannot cool off on the hot one. They move into the sun or into the shade as needed. During cooler pants of the year they become inactive. Because reptiles are cold – blooded. Reptiles reproduction also depends on temperature.
