Amazing Facts About Hippopotamus

Animals Mammals

The hippopotamus was named by the Greeks, which means “river horse”. Nevertheless, hippo is more closely related to pigs than horses. However, recent DNA evidences suggest that the hippopotamus is more closely related to cetaceans i.e. whales and dolphins. The hippopotamus is found in western, central, eastern and southern parts of Africa. They inhabit rivers, lakes, and wallows during the day. At night, hippos graze in short grasslands.  Their habitat ranges from Central and Southern Africa, Western Africa to south of the Sahara Desert. They are mostly found along the Nile River Valley and in game parks and reserves. Hippopotamus is the third largest animal on land, next to elephant and white rhino.

Amazing Facts About Hippopotamus

  • The hippopotamus is allied to pigs and hogs and has a very thick, naked skin, a thick and square head, a very large muzzle, small eyes and ears, thick and heavy body and short legs.
  • An adult male hippopotamus can weigh as much as 3200 kg (7000 lbs), but usually they weigh around 2300 kg (5000 lbs).  Adult females only weigh about 1800 kg (4000 lbs).
  • Even though hippos are so big, they only eat plants.  In a single night, a hippo can eat as much as 45.5 kg (100 lbs) of grass.
  • A hippopotamus does not sweat; rather it excretes an oily, red liquid that protects its skin. This red liquid has given birth to the myth that it sweats blood.
  • The hippo’s yawn is not a sign of sleepiness or boredom, but is actually a threat gesture, displaying long, thick, razor-sharp canine teeth, or tusks, with which it is capable of biting a small boat in half.
