The hippopotamus is herbivorous . They come out of the water at night to graze and can eat up to 100 pounds of vegetation in one night. Hippopotamuses will often travel up to six miles from their watering hole to find something to eat. The hippopotamus is found in West and East Central Africa. They inhabit the rivers and lakes throughout the grassland portions of this area.
Calves are in danger from lions, hyenas, and crocodiles.
The adult hippopotamus is usually too much for most predators to handle. Hippopotamuses live in groups of 15 or more animals. These groups are primarily females and their young headed up by a dominant male. There may also be some inferior males in these groups. The hippopotamus is territorial and once it establishes its territory it will attempt to chase off any interlopers .
