The elephant must drink between 170 and 230 liters per day but a single aspiration of its trunk can hold 15 liters. He takes advantage of the bath to drink and hydrate but also to play and communicate via an extremely developed communication system. Elephants can indeed talk by audible or non-audible sound emissions (infrasounds), visual signals from the ears, the trunk and the tail, by their general posture and by olfactory signals. They can also produce a viscous substance (musk) from their temporal glands to emit information of a different nature in males and females.
