hippopotamus, (Hippopotamus amphibius), amphibious African ungulate mammal. Often considered to be the second largest land animal (after the elephant), the hippopotamus is comparable in size and weight to the white rhinoceros (Ceratotherium simum) and the Indian rhinoceros (Rhinoceros unicornis).
Hippopotamus is Greek for “river horse,” and the animal has been known since ancient times. Hippopotamuses are often seen basking on the banks or sleeping in the waters of rivers, lakes, and swamps next to grasslands. Because of their great size and aquatic habits, they are safe from most predators but human beings, who have long valued their hide, meat, and ivory and at times have resented them for ruining crops. Once ranging over the entire continent and beyond, hippopotamuses (or “hippos”) now live in eastern, central, and parts of southern Africa.
The hippopotamus has a bulky body on stumpy legs, an enormous head, a short tail, and four toes on each foot. Each toe has a nail-like hoof. Males are usually 3.5 metres (11.5 feet) long, stand 1.5 metres (5 feet) tall, and weigh 3,200 kg (3.5 tons). In terms of physical size, males are the larger sex, weighing roughly 30 percent more than females. The skin is 5 cm (2 inches) thick on the flanks but thinner elsewhere and nearly hairless. Colour is grayish brown, with pinkish underparts. The mouth is half a metre wide and can gape 150° to show the teeth. The lower canines are sharp and may exceed 30 cm (12 inches).
Hippos are well adapted to aquatic life. The ears, eyes, and nostrils are located high on the head so that the rest of the body may remain submerged. The ears and nostrils can be folded shut to keep out water. The body is so dense that hippos can walk underwater, where they can hold their breath for five minutes. Although often seen basking in the sun, hippos lose water rapidly through the skin and become dehydrated without periodic dips. They must also retreat to the water to keep cool, for they do not sweat. Numerous skin glands release an oily reddish or pinkish “lotion,” which led to the ancient myth that hippos sweat blood; this pigment actually acts as a sunblock, filtering out ultraviolet radiation.

Hippos favour shallow areas where they can sleep half-submerged (“rafting”). Their populations are limited by this “day living space,” which may become quite crowded; as many as 150 hippos may use one pool in the dry season. In times of drought or famine, they may embark on overland migrations that often result in many deaths. By night, hippos walk...
In the wild, females (cows) become sexually mature between ages 7 and 15, and males mature slightly earlier, between ages 6 and 13. In captivity, however, members of both sexes may become sexually mature as early as ages 3 and 4. Dominant bulls more than 20 years old, however, initiate most of the mating.

Bulls monopolize areas in the river as mating territories for 12 years or more. Subordinate males are tolerated if they do not attempt to breed. Cows aggregate in these areas during the dry season, which is when most mating takes place. Rare battles may erupt when strange bulls invade territories in the mating season. Most aggression is noise, splash, bluff charges, and a yawning display of the teeth, but opponents may engage in combat by slashing upward at each other’s flanks with the lower incisors. Wounds can be fatal despite the thick skin there. Adjacent territorial bulls will stare at each other, then turn, and, with rear end out of the water, flip feces and urine in a wide arc by rapidly wagging the tail. This routine display indicates that the territory is occupied. Territorial and subordinate males alike make dung piles along pathways leading inland, which probably function as olfactory signposts (scent markers) at night. Hippos recognize individuals by scent and sometimes follow one another nose-to-tail on night treks.
Trampling and crop raiding by hippos led to early and determined efforts to exterminate them; their hides and meat were also valued. Hippos were extinct in northern Africa by 1800 and south of Natal and the Transvaal by 1900. They are still fairly common in East Africa, but populations continue to decrease continentwide. There remains a demand for ...
Feb 6, 2014 · But He made the hippos promise that if they lived in the rivers, they must never harm a single fish. They were to eat grass instead. God said that they were to show Him every night, that they were only eating grass. The Hippos promised solemnly, and rushed to the river, grunting with delight.
According to a San story, when the Creator assigned each animal its place in nature, the hippos wanted to live in the water, but were refused out of fear they might eat all the fish. After begging and pleading, the hippos were finally allowed to live in the water on the condition they would eat grass instead of fish, and fling their dung so it ...
Nov 12, 2018 · Hippos consume large quantities of grass on a daily basis, with some estimates suggesting that they can eat up to 150 pounds in a single night. Although hippos live in the water, they consume small quantities of aquatic plants. In the wild, hippos may also feed on available fruits.
There is an African legend that explains why Hippopotamus does not eat fish and it involves a promise made to the Lord N’gai who assigned creatures to their place.
