Reptiles (reptiles) are a group of vertebrate animals that are cold-blooded and have scales that cover their bodies. Reptiles are tetrapods (animals with four limbs) and spawn the embryo of the embryo by the amniotic membrane. Now they are living every continent except Antarctica.
The majority of reptiles are ovipar (spawn) although some species of Squamata are vivipar (childbirth). Vivipar reptiles feed their fetuses using a similar type of placent similar to mammals.
