|Binomial name||Hippopotamus amphibius|
Hippopotamuses (from the Greek for 'River Horse') are large herbivorous semi-aquatic African mammals, and the only four-toed ungulates. Once living in northern Africa, the hippopotamus is now only found south of the Sahara. The hippopotamus may have been the behemoth mentioned in Job 40:15-24. The hippopotamus and pygmy hippopotamus are the only living species, a small number of extinct species are also known from fossils.
Hippopotamuses may weigh up to 7000 pounds and reach 5 feet in height. They live in schools and submerge themselves in rivers to protect themselves from the sun, coming up for air every 5 minutes or so, although they are able to remain submerged for up to thirty minutes.
Hippos are born underwater and have to swim to the surface to breathe. They are also able to suckle underwater.
