Ungulates : Proboscidea
This order consists of two living species, which are among the best known in the entire world. Elephants are the largest land mammals in the world, with a strange nasal adaptation known as a trunk. An extremely versatile limb, the trunk is an extension of the nose and upper lip fused together. The extraordinary maneuverability of the trunk is due to the many layers of muscles - including modified forehead muscles, cheek muscles, nasal muscles, and lip muscles.
Elephants are classified as ungulates, even though it seems as if they walk flat footed. In actual fact they walk on their toes, with the heel cushioned by a wedge-shaped layer of fat-containing connective tissue. http://www.ultimateungulate.com
