What Is a Reptile?: Where Do Reptiles Live?

Reptiles are cold-blooded vertebrates similar to fish and amphibians. Their body temperature varies with the environment, making them less active in cold weather, often hibernating in winter. Reptile skin is tough and scaly, covered with protective scales that prevent dehydration. Unlike amphibians, reptiles have lungs and can live entirely on land. They lay eggs on land, with shells that protect the developing embryos from drying out.
