Elephant trunks have multiple functions, including breathing, olfaction, touching, grasping, and sound production. The trunk’s ability to make powerful twisting and coiling movements allows it to collect food, wrestle with other elephants, and lift up to 350 kg. It can be used for delicate tasks, such as wiping an eye and checking an orifice and is capable of cracking a peanut shell without breaking the seed. With its trunk, an elephant can reach items at heights of up to 7 m and dig for water under mud or sand. Individuals may show a lateral preference when grasping with their trunks: some prefer to twist them to the left, others to the right. Elephants can suck up water both to drink and to spray on their bodies. They will also spray dust or grass on themselves. When underwater, the elephant uses its trunk as a snorkel.
