    Reptiles are tetrapods. Limbless reptiles—snakes and other squamates—have vestigial limbs and, like caecilians, are classified as tetrapods because they are descended from four-limbed ancestors. Oviparous reptiles lay eggs enclosed in shells on land. Viviparous reptiles hold the eggs inside their body and give birth to live offspring. Even aquatic reptiles return to the land to lay eggs. They usually reproduce sexually with internal fertilization.
