One of the main reasons why elephants spray water is to cool down in hot weather. Elephants do not have sweat glands, so they use their trunks to spray water on themselves, which helps to regulate their body temperature. Elephants use water and mud to protect their skin from the sun and insects. They also use water to play and bond with each other, spraying each other or using trunk slaps in water to have fun as part of their behaviors. They’ve been seen spraying other animals as well for fun.
