Hippopotamidae – Hippopotamuses Family
The source says, Hippopotamus is the only surviving member of the hippopotamidae family. The hippopotamus is a stout, naked-skinned, and two-dimensional artiodactyl mammal with three chamfered abdomen and walk on four fingers on each leg. While they are anatomically similar to pigs, their closest living relatives are the Chitriya.
There are two living species of hippopotamus in two genera; Pygmy hippo, Quercopsis libreiensis of the West African forests and common hippos, Hippopotamus amphibius. The modern hippos are divided into two genera and two species. The genre is very different in size, so much so that one’s common name, Choeropsis liberiensis, Pygmy hippo. Nevertheless, all hippos are larger than most mammals, with larger species weighing 3600 kg and a further 250 kg approximately smaller. They are also similar in size, with large heads, round or barrel-shaped bodies and short, stumpy legs. Their skin is thick and almost hairless; Its pores infiltrate a pink substance known as blood sweat, which probably helps to protect against the sun. They have wide and square faces. The nose and eyes of their noses sit on top of their skulls so that the animal’s head is adorned and barely breaks the surface when they run out of water. Their tailings are short and tufted.
Properties
Hippopotamus is the only surviving member of the hippopotamidae family. Hippopotamuses are large mammals with small stout legs and barrel-shaped bodies that place their heads on large, broad mouths and on the nose pores of the nose. Like pigs, they have four fingers but unlike pigs, all toes are used for walking. Hippopotamids are regular, although different from other animals of this species, they have no nails, instead a pad of hard connective tissue is used on each leg. They have three chambers in their stomach but they are not true ruminants.
The living species is smooth skinned and lacks both the sebaceous gland and the sweat gland. The outer epidermis is relatively thin, so the hippos dehydrate quickly in a dry environment.
The incisor and the canine are both large and snow-like, although the tasks of the canine are much larger. Tasks grow throughout life. Postcannin teeth are large and complex, suitable for chewing plant foods containing their diet.
Hippopotamus amphibius
Origin
The hippopotamids originate from anthocrotheres, a family of semiotic and terrestrial artiodactyls that appeared at the end of the Eocene, and they seem to have analogous to small or narrow-headed hippies. Hippopotamus is the only surviving member of the hippopotamidae family. During the Miocene, the hippos separated from the anthracotheres. After the presence of the hippopotamid, the remaining anthrocautheres became a combination of climate change and competition with their offspring, until the last species, Mericopotamus, died in the Early Pliocene of India.
Hippopotamids once had many species, but only two survive today: Hippopotamus amphibius and Quercopsis libreiensis are the last survivors of the two major evolutionary lineages, the hippos apt and the pygmy hippos, respectively; These lineages may be arguably considered to be subfamily, but their relationship to one another – apart from fairly distant relatives – is not well resolved.
Description
The skull of the hippos is relatively large and long and the braincase is short. The orbits are higher above the skull. The hippos have a well-developed rich crest and asepitellar breeches, and an incomplete postorbital bar. The bones of the toes are unnecessary and the four toes of each foot are functional and support the body. The lateral digits are almost as advanced as the central hippos digitized, but only the distal phalanx of each toe touches the ground and the rest of the foot is bound by a pad of connective tissue. There are three chambers in the abdomen but they are uneven. Hippopotamus is the only surviving member of the hippopotamidae family.
The number of incisors is variable in both species and a common dental formula for the family is 2-5 / 3-5, 5/1, 5/1, 1/3 = 1-3. The task is to continually increase national incisors and canines. The lower incisors are larger and longer than the project forward.
The canines below are the largest of the slave national teeth and curve above the upper tooth row. The cheek teeth are progressively more complex in the back of the jaw. Premolars usually have a single casp, but this varies. The jaggery has two or three pairs of cusps that fall into the figures of the truffle, figure-eight, and dumbbell-shaped enamel. They are bunodont

Myosin keniopotamus is not known to adequately determine any location with any specificity in hippo phylogeny. In addition, the hexaprotodon tribe was, in one sense, confined to one of the extinct organisms inhabiting the North and Northeast Indian Ocean, where most ancient hippos were formerly included, which has been seen as paraphyletic.
Traits
Hippos are the greenest animals and live in up to 4 animals. They are both swimmers and great swimmers, they spend most of their time in the water and in the evening emerge to feed earthly plants. They also eat aquatic plants, which they can be immersed in by dipping and swimming.
Their terrain pastures may be a few kilometers away from where they spend the day, and they are sometimes responsible for considerable damage to crops and rangeland due to their pastureland and grazing areas. Pygmy hippos are less social and are usually found in the woodlands.
The historical range of both species included all sub-Saharan Africa, the Nile, Palestine, and even Madagascar. Fossil hippos are known from the late Miocene to the last Pleistocene deposits in Europe, Asia, and Africa. The hippopotamus is the only surviving member of the hippopotamidae family.
