Hippopotamidae - hippopotamuses
 There are two species in this family, the pygmy hippopotamus and the common hippopotamus. They are found in
lakes, swamps, and rivers in sub-Saharan Africa. Hippos have large heads; large, round bodies; small ears; and short tails. They have thick, gray skin lightly covered in hair and short, stumpy legs. Their ears, eyes, and nose are on the top of their heads. This lets the hippo submerge most of its body in water and keep it nose and eyes above the water line so it can breathe and keep an eye out for danger. The hippo lives in herds of up to 40 individuals. It spends most of the day in the water. At night, it emerges from the water to graze on vegetation. |
