An elephant's trunk is actually a long nose with many functions. It is used for smelling, breathing, trumpeting, drinking, and also for grabbing things—especially a potential meal. The trunk alone contains about 100,000 different muscles. Asian elephants have a fingerlike feature on the end of their trunk that they can use to grab small items. (African elephants have two.)
Elephants use their tusks to dig for roots and water, strip bark from trees, and even fight each other. Unfortunately their ivory has gotten them into a lot of trouble. Because ivory is so valuable to some humans, many elephants have been killed for their tusks. This trade is illegal today, but it has not been completely eliminated.
