Hippopotamuses, or hippopotami, are large, amphibious mammals.
Herbivorous, water-dwelling mammals, hippopotamuses live solely in bodies of water in Africa, most notably along the Nile river, where they commonly attack any animals perceived to be a threat to territory or offspring, including Crocodiles and humans. Hippopotamuses also resided in the Blue Nile river, which led out of Egypt and into Abyssinia.
