Hipopotammus

Hi, today we are going to talk about hipopotammus


The common hippopotamus (Hippopotamus amphibius) is a large artiodactyl mammal primarily herbivore that lives in sub-Saharan Africa. It is, along with the pygmy hippopotamus (Choeropsis liberiensis), one of only two current members of the Hippopotamidae family.

It is a semi-aquatic animal that lives in rivers and lakes, and where adult territorial males with groups of 5 to 30 females and young people control an area of the river. During the day they rest in the water or in the mud, and both the copulation and the birth of this animal occur in the water. At dusk they become more active and go out to eat terrestrial herbs. Although hippos rest together in water, grass is a solitary activity, and they are not territorial on land.

 Despite their physical resemblance to pigs and other terrestrial ungulates, their closest living relatives are the cetaceans (whales, porpoises, etc.) they diverged about 55 million years ago.

 The hippopotamus is easily recognizable by its torso in the form of a barrel, huge mouth and teeth, body with smooth and almost hairless skin, stubby legs and its large size. It is the third terrestrial animal by its weight (between 1½ and 3 tons), behind the white rhinoceros (1½ to 3½ tons) and the two genera of elephants (3 to 9 tons). Despite its squat shape and short legs, it can run as fast as an average human. Hippos have been timed at 30 km / h over short distances. It is one of the most aggressive creatures in the world and is often considered the most ferocious animal in Africa.
