White rhinoceroses wallow in mud baths to protect their skin and control their body temperature.
Because rhinoceroses are hairless mammals, they wallow in mud baths to protect their skin from the sun and help regulate their body temperature. They wallow most often when it’s hot.
They also dust bathe in sand baths during the winter, rub, and scratch themselves against objects, regularly visit salt licks, and readily enter swamps. They rarely take water baths. They can cool off by sweating, too, thereby losing moisture which they have to make up by drinking or by browsing water-rich plants.
