Hippopotamuses are large, round, water-loving animals that are native to Africa. The hippo’s proportions reflect its sedentary, amphibious existence. Its plump and bulky body is set on short, stumpy legs, with each foot having four toes. Although webbed, the toes splay enough to distribute the weight evenly over each toe and therefore adequately support the hippo on land. Two hippo species are found in Africa. The large hippo, found in East Africa, occurs south of the Sahara. This social, group-living mammal is so numerous in some areas that “cropping” schemes are used to control populations that have become larger than the habitat can sustain. The other, much smaller (440 to 605 pounds) species of hippo is the pygmy hippopotamus. Limited to very restricted ranges in West Africa, it is a shy, solitary forest dweller, and now rare.
