Hippopotamid
Hippopotamidae is a family of stout, naked-skinned, and semiaquatic artiodactyl mammals, possessing three-chambered stomachs and walking on four toes on each foot. While they resemble pigs physiologically, their closest living relatives are the cetaceans. They are formally referred to as hippopotamids. There are two living species of hippopotamid in two genera; the pygmy hippo, '' Choeropsis liberiensis'' of the forests of west Africa, and the common hippo, ''Hippopotamus amphibius''. The term ''hippopotamus'' can also be applied to hippopotamids in general, although it is most frequently used for the common hippo and its respective genus. Characteristics Hippopotamids are large mammals, with short, stumpy legs, and barrel-shaped bodies. They have large heads, with broad mouths, and nostrils placed at the top of their snouts. Like pigs, they have four toes, but unlike pigs, all of the toes are used in walking. Hippopotamids are unguligrade, although, unlike most other such ...

Choeropsis
The pygmy hippopotamus or pygmy hippo (''Choeropsis liberiensis'') is a small hippopotamid which is native to the forests and swamps of West Africa, primarily in Liberia, with small populations in Sierra Leone, Guinea, and Ivory Coast. It has been extirpated from Nigeria. The pygmy hippo is reclusive and nocturnal. It is one of only two extant species in the family Hippopotamidae, the other being its much larger relative, the common hippopotamus (''Hippopotamus amphibius'') or Nile hippopotamus. The pygmy hippopotamus displays many terrestrial adaptations, but like the hippo, it is semiaquatic and relies on water to keep its skin moist and its body temperature cool. Behaviors such as mating and giving birth may occur in water or on land. The pygmy hippo is herbivorous, feeding on ferns, broad-leaved plants, grasses, and fruits it finds in the forests. A rare nocturnal forest creature, the pygmy hippopotamus is a difficult animal to study in the wild. Pygmy hippos were unkn ...

Hippopotamus
The hippopotamus ( ; : hippopotamuses or hippopotami; ''Hippopotamus amphibius''), also called the hippo, common hippopotamus, or river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (''Choeropsis liberiensis'' or ''Hexaprotodon liberiensis''). Its name comes from the ancient Greek for "river horse" (). Aside from elephants and rhinos, the hippopotamus is the largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average ...

Artiodactyl
The even-toed ungulates (Artiodactyla , ) are ungulates—hoofed animals—which bear weight equally on two (an even number) of their five toes: the third and fourth. The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, odd-toed ungulates bear weight on an odd number of the five toes. Another difference between the two is that many other even-toed ungulates (with the exception of Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine as the odd-toed ungulates do. Cetaceans (whales, dolphins, and porpoises) evolved from even-toed ungulates, and are therefore often classified under the same taxonomic branch because a species cannot outgrow its evolutionary ancestry; some modern taxonomists combine the two under the name Cetartiodactyla , while others opt to include cetaceans in the already-existing Artiodactyla. The roughly 270 land-based even-toed ungulate species include pigs, peccaries, hippopo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saotherium
''Saotherium'' is an extinct genus of hippopotamid from the Early Pliocene of Africa, specifically Chad. It is represented by a single species, ''S. mingoz''. The earliest fossils appear at the start of the Pliocene, while the latest are dated to about 4 mya.

Kenyapotamus
''Kenyapotamus'' is a possible ancestor of living hippopotamuses that lived roughly 16 million to 8 million years ago during the Miocene epoch. Its name reflects that its fossils were first found in modern-day Kenya. Although little is known about ''Kenyapotamus'', its dental pattern bore similarities to that of the genus '' Xenohyus'', a European suid from the Early Miocene. This led some scientists to conclude that hippopotami were most closely related to modern peccaries and suids.Petronio, C. (1995): Note on the taxonomy of Pleistocene hippopotamuses. ''Ibex'' 3: 53-55PDF fulltext Recent molecular research has suggested that hippopotamuses are more closely related to cetaceans than to other artiodactyls. A morphological analysis of fossil artiodactyls and whales, which also included ''Kenyapotamus'', strongly supported a relationship between hippos and the anatomically similar family Anthracotheriidae.

Pachydermata
Pachydermata (meaning 'thick skin', from the Greek grc, παχύς, pachys, thick, label=none, and grc, δέρμα, derma, skin, label=none) is an obsolete order of mammals described by Gottlieb Storr, Georges Cuvier, and others, at one time recognized by many systematists. Because it is polyphyletic, the order is no longer in use, but it is important in the history of systematics. Outside strict biological classification, the term "" remains commonly used to describe elephants, rhinoceroses, tapirs, and hippopotamuses. Cuvier's Pachydermata included the three families of mammals he called Proboscidiana, Pachydermata Ordinaria, and Solipedes, all herbivorous. They are now divided into the Proboscidea (represented among living species only by three species of elephants), the Perissodactyla (odd-toed ungulates, including horses, tapirs and rhinoceroses), the Suina (pigs and peccaries), the Hippopotamidae, and the Hyracoidea ( hyraxes).
