Crocodiles recognize a pattern when animals come to the river to drink at the same time each day. That is why when on an Amazon River expedition DO NOT go to the same place at the same time every day to do your washing. You might end up as a crocodile snack. If you are ever on the coast Florida, remember not to swim at dusk when alligators are feeding, or on summer nights when they are most active. Fortunately, crocodiles are hungry only once every two weeks or so.
Crocodile attacks are the second biggest animal danger to people in Africa, next to the hippo.
All crocodilians swallow stones sometimes to help in digestion and add weight so that it can stay underwater. Crocodiles can remain submerged for as long as an hour. Because they are slow moving and cold blooded, they are able to survive on about the same amount of food as a small bird. A crocodile will attack just about anything that goes near the water, but sticks to eating fish most of the time, with occasional turtles, small animals and birds. They also enjoy tasty raccoons, muskrats and even capybara, the most popular treat of the South American caiman.
