The males are generally larger than the females. The crocodile's short stubby legs and webbed feet help it move on land, while its long powerfull tail helps it glide freely through the water. The crocodile's head has a large, long snout that has a row of deadly razor teeth attached to a pair of clamp-like jaws that can snap heavy boards in two. It keeps the water from entering through the mouth when the crocodile seizes its prey.
Crocodiles spend their lives in or close to water.
Most of them frequent freshwater lakes, rivers, or swamps, but some are found in coastal waters. Most crocodiles are found in the tropics, preferring large bodies of shallow water, sluggish rivers, open swamps, and marshes. On land, crocodiles run only for short stretches. Sometimes, they travel overland to get from one waterway to another. They also leave the water to sun, to rest, and to wait for prey.
