They eat just about anything from insects and small birds to sharks, and other large mammals that might come into their territory. Some crocodiles feed on large mammals and some feed on smaller ones, but most prefer vertebrate animals, while others eat on invertebrates. The crocodiles that usually eat the smaller animals are usually younger, and the larger crocodiles are the crocs that eat the much larger animals. All crocodiles have their own food they prefer. In fact most people suggest that the human might be attacked when bending over a part of water and the crocodile might think of them as a big animal such as the antelope, and that s why attacks on humans occur.
Crocodiles also consume more food in the summer than they do in the winter.
How crocs adapt to environment All crocodiles are very well adapted to the land as well as they water. Crocodiles are excellent swimmers and get there swimming speed from there long sleek tail they wipe back and forth under water why there feet are tucked towards there belly. Crocodiles swim and float on the surface of the water, exposing there nostrils, eyes, and flat tails. For submerging under water to look for food crocodiles use there transparent third eye lid, other than the normal upper and lower eyelids, for finding food in the water and on the floor bottoms. Crocodiles can dive for long periods of time, and to help sense prey under the water, crocodiles use vibration sensors and touch receptors to catch the moving prey in the water.
