Reptiles

The most noticeable feature of reptiles are the scales that cover their body. Although reptiles breathe through lungs, some reptiles can also absorb oxygen in water through membranes in their mouth.

Reptiles are often called cold-blooded because they can`t regulate their own body temperature. Their body temperature depends on the external temperature.

Crocodiles and alligators are large amphibious reptiles. They can walk on land using their webbed feet. They can also use their long tail to swim in water. Crocodiles feed on large animals they catch on land or in water. They have powerful jaws and teeth to tear apart their prey.

Lizards and snakes are the largest group of reptiles. Lizards are four legged animals with a long tail. Many lizards can shed their tail to escape from predators. They can then grow a new tail.
