Reptiles are cold-blooded animals with bodies covered in scales or plates. Most reptiles live on land, but some live in the ocean and fresh water habitats. All reptiles get the oxygen they need from air

Reptiles are classified into three main groups:

• crocodiles and alligators.
• snakes and lizards.
