Reptiles are animals in the (Linnaean) class Reptilia characterized by breathing air, a "cold-blooded" (poikilothermic) metabolism, laying tough-shelled amniotic eggs, and skin with scales or scutes. They are tetrapods and lay amniotic eggs, in which the embryo is surrounded by a membrane called the amnion.
