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.
