Normal hippopotamus, or Hippopotamus amphibius
Origin and features
one of the biggest current land creatures: the heaviness of old guys can surpass 4 tons, the body length is 3.5 meters. Already, pigs were viewed as the nearest family members of hippos, however present day research has shown that as a matter of fact they are cetaceans. What's more, the actual hippos are basically semi-sea-going creatures: they burn through the greater part of their lives in the water, and emerge ashore just around evening time for a couple of hours to take care of. Of course, the antiquated Greeks referred to them as "stream ponies" (the strict interpretation of "hippo"), the Middle Easterners - "waterway bison", and the Egyptians, all the more exactly, "waterway pigs". Submerged, hippos can keep awake to thirty minutes, despite the fact that they as a rule plunge for just 3-5 minutes. They swim, for the most part paddling with their rear legs, yet more frequently they basically stroll along the base, utilizing their enormous explicit grvity.
Appearance and nutrition
The body of the hippopotamus is barrel-molded, and the legs are extremely short and thick, with four fingers covered with hooves, joined by a little film. The colossal quadrangular top of the stream bison arrives at a fourth of its all out mass (up to 900 kg) by weight; nostrils, eyes and ears are to some degree brought and situated up in a similar plane, so the hippopotamus can inhale, look and hear, remaining totally submerged and uncovering just the actual top of the head (f. 3). His eyes are little and encircled by thick eyelids, and extremely wide, upwardly coordinated nostrils, ready to close firmly because of the beefy edges and advanced exceptional muscles. The skin of this creature has for all intents and purposes no hairline, and there are organs on it that emit confidential of a surprising red tone, like ridiculous perspiration. This is a particular mucous oil that gives the skin flexibility and safeguards it from drying out ashore and unnecessary expanding in water. The mouth of the hippo is likewise extraordinary: it opens with the goal that the point between the jaws is around 150 degrees; the teeth are seldom divided, the teeth on the lower jaw don't have roots, develop over the course of life and can arrive at a length of 65 cm.
Hippos feed fundamentally on delicious vegetation developing along the banks of repositories, and eat up to 40 kg each day. Their incredibly lengthy (around 60 m) intestinal system and three-loaded stomach make it conceivable to process this gigantic mass of fiber.
