Hippopotamus

The Greeks called them “river horses." Eyes and nostrils on top of the head help this behemoth — the third largest land mammal — see and hear while in water up to 16 hours a day. At night, hippos graze, consuming about 80 pounds of grass.

Hippos once populated lakes and rivers throughout sub-Saharan Africa. Today, they are mostly found in eastern and southern Africa.
