The trunk combines both nose and upper lip and transforms them into a single powerful organ that is able to touch, grasp and smell. It is strong enough to uproot a tree, sensitive enough to pick up a pea-sized fruit from the ground, and long enough to reach foliage high in the trees. The trunk is also used to drink by sucking up water and squirting it into the mouth. Finally, elephants use their trunks for greeting, caressing, threatening, and throwing dust over the body.
The elephant's trunk has about 15,000 muscles and it takes baby elephants quite some time to learn to master its use.
