Crocodiles are carnivorous aquatic animals, usually eating fish, rabbits, frogs, deer, waterfowl and so on. They are aggressive and many animals are no match for them because they have sharp teeth and a big mouth.

According to the relevant information, crocodiles generally know the location of their prey by climbing, or come into contact with places with light as much as possible.

Crocodile is a kind of variable temperature aquatic animals, basically can not produce body heat, with the help of the outside world to reach a certain temperature. So you often have to climb to a place where there is light to keep your body warm. If the temperature is high in summer, you have to hide under the shade or where there is water in order to lower the temperature of the body. If you do not have access to water for a long time and are exposed to the sun, it will not take a long time to die because the heat cannot be released.
