Elephant trunks can grow up to 2 meters long and serve multiple purposes beyond just smelling. They are used for eating, drinking, spraying water and dust on their bodies, and grasping objects. African elephants live in herds across much of the continent south of the Sahara. Their pregnancies are the longest of any animal at 22 months. Elephants can live up to 70 years and eat a variety of plants like fruit, bark, grass, and leaves.
