Elephants have long trunks because they need them in order to survive on the savannah or in the rainforest. Elephants use their trunks for many different purposes such as digging for water and spraying dust over their bodies.
Elephant trunks are very strong and have two finger-like grips on the tip. This allows an elephant to pick up small objects such as a peanut or large objects such as tree trunks. Elephants use their trunks for basic functions such as breathing and spraying water into their mouths, but also use their trunks to caress other elephants or keep young elephants in line.
