Since African elephants live where the sun is usually blazing hot, they use their trunks to help them keep cool. First they squirt a trunkful of cool water over their bodies. Then they often follow that with a sprinkling of dust to create a protective layer of dirt on their skin (think elephant sunscreen!). Elephants pick up and spray dust the same way they do water—with their trunks.
Rajan is one of the few salt water swimming elephants on Earth. He lives in the Andaman Islands with his mahout, or caretaker. He and many others were once employed to swim logs from the outer islands for the logging industry. He is now the only survivor of that group.
