Man-eater is a colloquial term for an animal that preys upon humans. This does not include scavenging. Although human beings can be attacked by many kinds of animals, man-eaters are those that have incorporated human flesh into their usual diet. Most reported cases of man-eaters have involved tigers, leopards, lions and crocodilians. However, they are by no means the only predators that will attack humans if given the chance; a wide variety of species have also been known to take humans as prey, including bears, large constricting snakes (such as boas and pythons), Komodo dragons, wolves, hyenas, cougars, sharks, and even other humans.
