Hippopotamus (from the Greek ἱπποπόταμος, composed of ιππος, “horse”, and ποταμού, “river”) the generic name of a large ungulate mammal belonging to the family Hippopotamidae. It is a artiodátilo mammal, typical of Africa, the skin too thick and naked, legs and tail short, head very large and a truncated nose broad and rounded.
Hippos spend most of their days in the water or mud with the other members of their group. Water is meant to keep your body temperature low and not to let your skin get dry. Most hippos live fighting with other hippos and their reproduction occurs in water.
Hippos come out of the water at dusk and travel inland, sometimes up to 8 km, to graze on short grass, their main source of food. These large animals can consume 68 kg of grass each night. Like any herbivore, they will consume many other plants, but their natural diet is made up mostly of grass, with only minimal consumption of aquatic plants. Hippos have already (rarely) been filmed eating carrion, usually near water. There are other reports of meat-eating, and even cannibalism and predation. A hippo’s stomach anatomy is not suitable for carnivory and meat-eating is probably caused by aberrant behavior or nutritional stress.
The hippo diet consists mainly of terrestrial grasses, even though they spend most of their time in the water. Because of their size and habit of taking the same paths to feed, hippos can have a significant impact on the earth by keeping the land clear of vegetation and pressing the ground. For prolonged periods, hippos can divert the paths of marshes and canals.
When they spend a lot of time in the sun, they burn. That’s why they take a mud bath to hydrate themselves.
They may be very clumsy out of the water, but inside they are like very delicate dancers.
Adult hippos usually come out of the water to breathe every 3-5 minutes. Adult hippos move at speeds of up to 8 km per hour while in the water. Young people have to breathe every two to three minutes. The breathing process is automatic, and even if he sleeps he will rise and breathe without waking up. A hippo closes its nostrils when it submerges itself.
As with fish and turtles on a coral reef, the hippo sometimes visits “cleaning stations”, and there when it opens its mouth it is a sign that fish can clean up parasites in its mouth. For many fish, these parasites are food.
