Habitat

Crocodiles live mainly in rivers, lakes, or shallow water. Some can be found in brackish water, or salt water mixed with fresh water, such as coastal lagoons, and mangrove swamps. Crocodiles are found in warmer climates. You will most likely see them in Southern Florida, Southern Mexico, Central America, the Caribbean, or Northern South America. (Sirs Discoverer).You might see other kinds of crocodiles in other places, but these are the main places you will find them.

Movement

Crocodiles have webbed feet, which allows them to walk on the ground. The crocodiles's eyes are higher than the rest of the head. These features enable the animal to float in the water, with only their eyes and nostrils above the surface. Crocodiles also have partly clear inner eyelids, enabling them to see underwater without damaging their eyes. A crocodiles throat has a slit - like valve in front of the tube leading to it's nostrils. The valve shuts tight when the animal is underwater, and it keeps the water from entering through the mouth when the reptile is seizing it's prey. (World Book Advanced).

Body Covering

Crocodiles have tough, scaly skin, that is a gray-green or olive-green in color. They have flattened bodies and tails, short legs, and very powerful jaws. The eyes, ears, and nostrils are located near the top of the head, very sharp claws. Crocodiles have up to 68 teeth. The ears and nostrils have valves that close when the animal is submerged. They also have very strong tails, which help them when they swim. (Sirs Discoverer). The crocodiles also have pointed snouts, unlike alligators. You can tell the difference between them, because alligators have rounded snouts, instead of a pointed snout like crocodiles. The crocodile is cold-blooded. The body temperature of a cold-blooded animal changes with the temperature of it's surroundings. (World Book Kids).

Diet

Crocodiles are carnivores. They eat fish, birds, mammals, and sometimes even smaller crocodiles. These reptiles occasionally attack large animals and people. A crocodile can twist a large animal into pieces by seizing it, and then rapidly spinning lengthwise in the water. (World Book Advanced).

Reproduction

The female crocodile deposits her eggs, usually about 20 in a number, in a nest of rotting vegetation or in a shallow pit on the river bank, and digs them up when she hears them hatching. (Gale Research). Crocodiles lay their eggs with leathery shells. They hide their eggs in the sand or in nests made of plants. (World Book Kids).

Adaptations

Crocodiles are ambush hunters. They blend into the water so well, no animal can see them. They hide beneath the surface of the water, and they strike without warning. They drag their prey underwater to drown and kill them. As cold-blooded predators, they can survive without food, for long periods of time. (Web path Express).
