>For other uses, see Tiger (disambiguation). Tigers (Panthera tigris) are mammals of the Felidae family and one of four "big cats" in the Panthera genus. A group of tigers is called an "ambush" or a "streak". They are predatory carnivores and the largest of all living cats. Most tigers live in forests and grasslands (for which their camouflage is ideally suited). Among the big cats, only the tiger and jaguar are strong swimmers, and tigers are often found bathing in ponds, lakes and rivers. Tigers hunt alone and eat primarily medium-sized herbivores such as deer, wild pigs, and buffalo. However, they will also take larger or smaller prey on occasion. Humans are the tiger's only serious enemy and often kill tigers illegally for their fur or penises, which are used as aphrodisiacs in Chinese Medicine. Poaching for fur and destruction of habitat have greatly reduced tiger populations and it has been placed on the endangered species list. See more at Wikipedia.org...
