INTRODUCTION
4. REPRODUCTION
Reptiles are oviparous animals. The mothers lay eggs. Then the babies grow inside
the eggs. Later , the eggs break open and the babies come out.
Crocodiles lay eggs. Mothers make a nest. It may be a hole in the sand or a small
mountain of dirt and dry leaves, grass and other parts of the vegetation.
5. BODY COVERING
Reptiles, and birds or mammals have scales to protect their bodies against the
cold . Snakes shed their skin every year to get rid of the wounds of parasites.

tract. Some reptiles eat vegetables.
