Elephants full of… Mud!
The African elephant (Loxodonta africana) is the biggest terrestrial animal in the world. Males weight about 7 tonnes, while females about 4 tonnes! Such a huge bodies need more than one system to cool . One way is the big ear flaps which full of blood vessels. Like a big radiator whenever it is too hot, the elephant flap his ears, and the blood is being cooled. One more way to cool the body is through the folded skin, which enable evaporation. Another way is to spend the hot hours of the day in a water pool. But if no pool around, then the mud can do. Mud also helps against insects bites.
