Hippos cannot sweat like humans do.All hippos,however,ooze a type of oil from their skin.A river hippo’s natural skin oil is red.People used to think these animals sweated blood,but that’s not true.
A hippo’s skin oil is like lotion.Hippos have thin skin for such big mammals,and it dries out easily.The oil keeps a hippo’s skin from cracking in the heat.
