5 - Crocodile
There is nothing more frightening than a predator that lurks underwater for its prey, camouflaged by the surrounding environment, silently watching its victim and planning its kill. No. 5 in our countdown is the crocodile, a stealthy and extremely violent predator. With long, powerful jaws and teeth, the crocodile preys on a variety of animals. Some species, such as the Nile crocodile, can bring down very large prey such as zebras and buffalo. Its typical mode of attack is to wait at the water's edge for an animal to come to drink and then drag the hapless creature underwater and begin spinning around forcefully and repeatedly in order to tear off chunks of flesh.
