They usually move slowly over land but in short bursts can cover ground rapidly. Most of their time, however, is spent in the water. They adore basking in the sunshine along the banks of rivers, streams, and ponds. Crocodilians in the water are largly hidden, resembling from above floating logs. This unassuming appearance allows them to move close to shore and seize animals that come to the water to drink.
Crocodilians are meat-eaters.
The foods taken depend on their age and size. Adult American Crocodiles, which often forage at night, specialize on fish and turtles. Crocodilians may use vocal signals extensively in their behavior, in communicating with one another, but their sounds have been little-studied. It is known that juveniles give alarm calls when threatened, and that parents respond by quickly coming to their rescue. Surprisingly, however, crocodilians show varying degrees of parental care.
