What groups do Reptiles include?
Crocodilia is a group of reptiles that can grow quite large, and includes alligators and crocodiles. Normally found near the water in warmer climates, Crocodilia might be more closely related to birds than other reptiles.
Squamata is the order of reptiles that includes snakes and lizards. Snakes are special because they have no legs and no ears. They feel vibrations, smell with their tongues, have specialized scales, and can unhinge their jaws to swallow prey that is larger than they are. Like snakes, lizards have scales, but they differ in that they have legs, can dig, can climb trees, and can grab things.
Chelonia is the order of reptiles that includes turtles and tortoises. It is a special group because its members have shells. Different varieties live in forests, water, and deserts, or anywhere the climate is warm enough. They also live a long time, even hundreds of years. Turtles are typically found near water and tortoises on land, even dry areas.
