Elephantidae is a taxonomic family, collectively elephants and mammoths. These are terrestrial large mammals with a trunk and tusks. Only two genera, Loxodonta (African elephants) and Elephas (Asiatic elephants), are living.
The African Bush Elephant is the largest living terrestrial animal, normally reaching 6 to 7.3 metres in length and 3 to 3.5 metres in height at the shoulder, and weighing between 6,000 to 9,000 kg.The animal is characterized by its large head; two large ears that cover its shoulders and radiate excess heat; a large and muscular trunk; two prominent tusks, which are well-developed in both sexes, although more commonly in males; a short neck; a large, barrel-like body; four long and heavy legs; and a relatively short tail.The animal is protected by a heavy but flexible layer of gray-brown skin, dotted with mostly undeveloped patches of hair and long, black hair at the tip of its tail. Its back feet have three toes that form a hoof, while the number of toes on the front feet have varied between four and five.

It is amazing, that the three living species of elephants and the mammoth differ from all the other mammals in their trunk.
