The African elephant is the largest living land mammal. Of all its specialized features, the muscular trunk is perhaps the most extraordinary. It serves as a nose, hand, extra foot, signaling device and tool for gathering food, siphoning water, dusting, and digging. The tusks are another notable feature of both males and females. Elephants are right or left-tusked, using the favored tusk more often, thus shortening it from constant wear. Tusks differ in size, shape and angle and researchers can use them to identify individuals.
