Describes their habits with links to other sites. Also includes pictures of hippos, with a map of where they live. The river hippopotamus spends most of the day wallowing, resting, and swimming in or near water. At night, they emerge from the water to graze. Hippos will graze about 3 kilometers 1.8 miles from water, although some individuals move further inland. An individual may walk 10 kilometers 6 miles to seek food on land, spending an average of 56 hours on land per night. Despite their bulk, they can run extremely fast. A river hippos daily consumption is 11.5 percent of its body weight, compared to an average of 2.5 percent for most other ungulates. Well at home in the water, their specific gravity allows them to walk along the bottom and makes it difficult for them to truly swim. When submerged, they can seal off their slitlike nostrils and ears. The shape of their head is much like that of a frog, and allows them to keep their eyes and nostrils above the surface, while keeping the rest of their body submerged.
