The Hippopotamus ("Hippo"), from the ancient Greek for "river horse" is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopatamidae (the other is the Pygmy Hippo). After the African Elephant the hippotamus is the largest land mammal and the heaviest extant artiodactyl, despite being considerably shorter than the Giraffe.Male hippopotamuses (or hippo for short) mark their territory by flicking dung around. Male hippos also, to mark their territory, poo in their water so other male hippos know not to go there. Hippos show off their big teeth with a mammoth yawn that says, "If you don't stay away, these teeth are going to come in handy!"
