Turtles are recognized as the oldest proven reptile group and facts show that they are even older than the dinosaurs. Crocodiles come in second as the oldest reptile group.
Although reptiles breathe through lungs, some reptiles can also absorb oxygen in water through membranes in their mouth. The scale which covers a reptile’s body is the most noticeable feature of a reptile. Their scaly skin is necessary to protect their bodies from the rough surface of the ground.
