Hippopotamus yawns in small spring water pool, Serengeti, Tanzania
During the dry season, natural spring water ensures a steady flow of water for the wildlife of the Serengeti. Yet still, space is limited, thus water-bound animals need to share. This small water pool is crammed with hippos and crocs.

The hippopotamus, or hippo, is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae. The name comes from the ancient Greek for "river horse". After the elephant and rhinoceros, the hippopotamus is the third-largest type of land mammal and the heaviest extant artiodactyl.
