The hippopotamus
The Hippopotamus, also known by its scientific name Hippopotamus amphibius, is an impressive animal that lives in freshwater areas in Africa. Unlike other animals in this region, the hippopotamus is adapted to live both in water and on land. With a weight between 1.5 and 3.5 tons and a length of up to 4 meters, it is one of the largest land mammals. We will now explore in more detail the fascinating characteristics and behavior of the hippopotamus.The hippopotamus has a large, round body covered in thick, gray or brown skin that is hard to penetrate. A notable feature of this animal is that it has short legs compared to its body size, which gives it excellent stability in water. The hippopotamus's nose is located on the top of its head, allowing it to easily breathe while submerged in water when it sleeps, with only its nostrils above the surface.
Hippopotamuses show sexual dimorphism, meaning that males are larger than females. They also have prominent canines that can reach up to 51 centimeters in length and can be projected forward to defend their territory or females. The position and size of these canines make them some of the most dangerous animals in Africa. However, despite their intimidating appearance, hippos are generally docile animals and do not attack humans, except when provoked or when they feel their offspring are threatened.
Hippos are adaptable and can live in various types of aquatic environments, including rivers, lakes, ponds, or swamps. This is due to their thick skin, which allows them to better withstand dehydration and extreme temperatures. They also have special glands that secrete a red oil, protecting them from excessive sun exposure. Furthermore, hippos are excellent swimmers and can stay underwater for up to six minutes, during which they can close the valves of their ears and nose to prevent water from entering these openings.
The main food of the hippopotamus consists mainly of aquatic plants, such as grasses, herbs, and other vegetation that grows in water. These water giants spend a significant amount of time in water and can submerge to feed on water hyacinths or plants that grow in shallow water. However, hippos are herbivores and consume a large amount of food throughout the day. They require approximately 68 kilograms of food daily to maintain their body weight.
The social behavior of the hippopotamus is also interesting to study. These animals live in groups known as "pods," which are led by a dominant male. The group can consist of 10 to 30 individuals and sometimes even more. Males will use territorial marking and threats to maintain their dominance within the group. Additionally, they communicate with each other through sounds such as grunts and songs.
Like other wild animals, hippos face threats to their natural habitat. Excessive hunting and habitat loss, for example, are major issues facing these animals. Fortunately, efforts are being made to protect them through nature reserves and conservation legislation. Additionally, education and public awareness play a crucial role in ensuring the protection of these wonderful animals.
In conclusion, the hippopotamus is a fascinating animal species, adapted to live both in water and on land. Their massive size, social behavior, and unique adaptations make the hippo an animal worth getting familiar with and protecting. Understanding and conserving their habitat is essential to ensure their survival in the wild and preserve the biodiversity richness of Africa.

Facts
The hippopotamus (Hippopotamus amphibius) is an African amphibious mammal, the largest non-ruminant. Its name comes from the Greek language, having the meaning of river horse (hippos = horse, potamus = River).
Soil encroachment and crop destruction by hippos have led to efforts to exterminate them – skin and meat are also prized. Hippos disappeared completely from North Africa by the 1800s and from Southern Natal and Transvaal by 1900.
They are still quite widespread in Eastern Africa, but for example the Lake Chad breed in central-West Africa is threatened with extinction. Hippo populations are constantly declining.
There is still a high demand for hippo teeth as a source of fine ivory that can be easily processed – it was once used to make false teeth.
Feeding Hippopotamus
At night the hippos walk on trails known to them, up to 10 km in the pastures around the water, to feed for 5-6 hours. Long canines and incisors are used only as a weapon – grazing is performed by grabbing the grass with wide, hard lips and jerking the head vigorously.
Near rivers, where grass is grazed intensively and trampled, large areas can become completely devoid of vegetation, which leads to erosion. However, hippos eat quite little compared to their body weight (about 35 kg per night) because their energy needs are low as a result of spending most of their time in warm water.
Hippos do not rummage, but retain food for a long time in the stomach, extracting proteins through fermentation-based digestion process. Their digestive process is responsible for releasing a large number of nutrients into African rivers and lakes, thus favoring fish, which are in turn a crucial protein source for the local human population.
Appearance Hippopotamus
It has a barrel-shaped body, an enormous mouth, short legs and four toes on each foot. It can reach a length of 3.5 m, a shoulder height of 1.5 m and a weight of 3,200 kg.
The skin is very thick, almost hairless, a grayish-brown color on the back, but lighter, pink, on the ventral side. The ears and nostrils remain on the surface of the water when the rest of the body is submerged.
Hippos live near rivers, lakes, swamps, or other water meshes, usually in groups of 7 to 15 individuals.
There is no obvious sexual dimorphism, so females and young males are often confused.
Hippo Behavior
During the day they sleep and rest in or near the water. At night they go ashore to feed on herbs. In the water they can swim quickly or even go to the bottom, because they can stay submerged (with their nostrils and ears plugged) for more than 5 minutes.
Although they can often be seen lounging in the sun, hippos dehydrate quite quickly and need water to rehydrate their skin. Water is also needed to cool their bodies because they don't sweat.
Their skin is endowed with numerous glands that secrete a substance of reddish color, which led to the emergence of an ancient myth that hippos would sweat blood. The substance secreted by these glands acts as a filter against ultraviolet rays.
Hippos like shallow waters in which they can sleep only half submerged. The number of specimens is limited by these breeding spaces, which can become quite crowded – up to 150 hippos can share the same pool during the dry season.
During severe droughts or famines they start long migrations, which often result in the death of many specimens.
Females live in flocks, but do not associate permanently with other females, although they sometimes keep in touch with their offspring for several years. When in proximity, the dominant males from neighboring territories stare at each other, then turn around and, with their hind parts removed from the water, vigorously remove feces and urine in a wide arc.
This behavior indicates that the territory is occupied. The other males in the territory also make piles of dung along the access routes to their area, marking it olfactively. Hippos recognize each other by smell and sometimes follow one another, with their noses close to the tail of the one in front, on night trips.
Rarely do male disputes occur when foreign Bulls invade mating territories. Most aggressions consist of noises, showering with water, false attacks and displaying teeth by wide yawning of the mouth, but sometimes opponents engage in violent battles, trying to tear their opponent from the side with their lower incisors.
Wounds can be fatal despite thick skin.
Hippo Breeding
Males mature at the age of 8, but most mating is done by dominant males over the age of 20.
They monopolize for 12 years or more areas of the Rivers, called Mating territories. Other males are tolerated, but only if they do not attempt to mate. Females gather in these areas during dry periods, when most mating occurs.
Females Mature at 3 years of age in zoos, but in the wild maturity does not occur until after the age of 13. After an eight-month gestation, a single calf is born, weighing about 45 kg.
The calf can close its ears and nostrils to feed underwater and can climb onto its mother's back to rest. It begins to eat grass at the age of one month and is weaned at the age of 6-8 months.
Females give birth to a calf every two years. Young calves are vulnerable to crocodiles, lions and hyenas.
Longevity is up to 49 years in captivity, but rarely exceeds 40 years in the wild.
