Asinus
''Asinus'' is a subgenus of '' Equus'' (single-toed (hooved) grazing animal) that encompasses several subspecies of the Equidae commonly known as wild asses, characterized by long ears, a lean, straight-backed build, lack of a true withers, a coarse mane and tail, and a reputation for considerable toughness and endurance. The common donkey is the best-known domesticated representative of the subgenus, with both domesticated and feral varieties. Among the wild ass species, several never-domesticated species live in Asia and Africa.

Donkey
The domestic donkey is a hoofed mammal in the family Equidae, the same family as the horse. It derives from the African wild ass, ''Equus africanus'', and may be classified either as a subspecies thereof, ''Equus africanus asinus'', or as a separate species, ''Equus asinus''. It was domesticated in Africa some years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding or as pets in developed countries. A male donkey is known as a ''jack'' or ''jackass'', a female is a ''jenny'' or ''jennet'', and an immature donkey of either sex is a '' foal''. Jacks are often mated with female horses (mares) to produce '' mules''; the less common hybrid of a male horse (stallion) and j ...

African Wild Ass
The African wild ass (''Equus africanus'') or African wild donkey is a wild member of the horse family, Equidae. This species is thought to be the ancestor of the domestic donkey (''Equus asinus''), which is sometimes placed within the same species. They live in the deserts and other arid areas of the Horn of Africa, in Eritrea, Ethiopia and Somalia. It formerly had a wider range north and west into Sudan, Egypt, and Libya. It is Critically Endangered, with about 570 individuals existing in the wild. Description The African wild ass is about tall and weighs approximately . The short, smooth coat is a light grey to fawn colour, fading quickly to white on the undersides and legs. There is a slender, dark dorsal stripe in all subspecies, while in the Nubian wild ass (''E. a. africanus''), as well as the domestic donkey, there is a stripe across the shoulder. The legs of the Somali wild ass (''E. a. somaliensis'') are horizontally striped with black, resembling those of a zebra. O ...

Equus (genus)
''Equus'' , is a genus of mammals in the family Equidae, which includes horses, donkeys, and zebras. Within the Equidae, ''Equus'' is the only recognized extant genus, comprising seven living species. Like Equidae more broadly, ''Equus'' has numerous extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than ruminants but able to subsist on lower-quality vegetation. While the domestic horse and donkey (along with their feral descendants) exist worldwide, wild equine populations are limited to Africa and Asia. Wild equine social systems are in two forms; a harem system with tight-knit groups consisting of one adult male or stallion, several females or mares, and their young or foals; and a terr ...

Nubian Wild Ass
The Nubian wild ass (''Equus africanus africanus'') is the nominate subspecies of African wild ass, and one of the ancestors of the domestic donkey, which was domesticated about 6,000 years ago. It is presumed to be extinct, though two populations potentially survive on the Caribbean island of Bonaire and in Gebel Elba. Description According to Groves & Chubb, Nubian wild asses had longer ears than the Somali wild ass, ranging from 182-245mm in length. These animals also possessed the "cross-pattern" famous in domestic donkeys but absent in the Somali subspecies, and lacked the "zebra-stripe-pattern" on the legs as found in Somali specimens. Habitat and distribution Nubian wild asses lived in the Nubian Desert of northeastern Sudan, from east of the Nile River to the Red Sea and south to the Atbarah River and northern Eritrea. Extinction and potential survival The Nubian wild ass has not been seen since the 1950s-70s and is presumed extinct. The last sighting of wild asses in th ...

Somali Wild Ass
The Somali wild ass (''Equus africanus somaliensis'') is a subspecies of the African wild ass. It is found in Somalia, the Southern Red Sea region of Eritrea, and the Afar Region of Ethiopia. The legs of the Somali wild ass are striped, resembling those of its relative, the zebra. Current distribution and habitat There are likely fewer than 1,000 animals (or even 700) in the wild and the ''International Union for Conservation of Nature, IUCN Red List of endangered species'' described it as "critically endangered". This means they face an extremely high risk of extinction in the wild. A few hundred specimens live in Somalia, Somaliland, Eritrea and Ethiopia. Reproduction Somali wild asses typically give birth in the spring, a common characteristic among equids, after a year-long gestation. Within hours, the foal is up on its legs and keeping up with its mother. At around five days old, the foal is already nibbling grass. By the time its two weeks old, the foal is grazing regular ...

Equidae
Equidae (sometimes known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, asses, and zebras, and many other species known only from fossils. All extant species are in the genus '' Equus'', which originated in North America. Equidae belongs to the order Perissodactyla, which includes the extant tapirs and rhinoceros, and several extinct families. The term equid refers to any member of this family, including any equine. Evolution The oldest known fossils assigned to Equidae were found in North America, and date from the early Eocene epoch, 54 million years ago. They were once assigned to the genus ''Hyracotherium'', but the type species of that genus is now regarded as a palaeothere. The other species have been split off into different genera. These early equids were fox-sized animals with three toes on the hind feet, and four on the front feet. They were herbivorous browsers on relatively soft plants, and already adapte ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onager
The onager (; ''Equus hemionus'' ), A new species called the kiang (''E. kiang''), a Tibetan relative, was previously considered to be a subspecies of the onager as ''E. hemionus kiang'', but recent molecular studies indicate it to be a distinct species, having diverged from the closest relative of the Mongolian wild ass's ancestor less than 500,000 years ago. Subspecies Five widely recognized subspecies of the onager include: A sixth possible subspecies, the Gobi khulan (''E. h. luteus'', also called the ''chigetai'' or ''dziggetai'') has been proposed, but may be synonymous with ''E. h. hemionus''. Debates over the taxonomic identity of the onager occurred until 1980. , four living subspecies and one extinct subspecies of the Asiatic wild ass have been recognized. The Persian onager was formerly known as ''Equus onager'', as it was thought to be a distinct species. Characteristics Onagers are the most horse-like of wild asses. They are short-legged compared to horses, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongolian Wild Ass
The Mongolian wild ass (''Equus hemionus hemionus''), also known as Mongolian khulan, is the nominate subspecies of the onager. It is found in southern Mongolia and northern China. It was previously found in eastern Kazakhstan and southern Siberian Federal District, Siberia before being extirpated there through hunting. As of 2015, the Mongolian wild ass is listed as Near Threatened by the IUCN. Current population estimates are approximately 42,000 individuals in Mongolia and around 5,000 individuals in Northern China. Taxonomy and etymology The Mongolian wild ass is synonymous with the Gobi khulan (''Equus hemionus luteus''), also called the ''chigetai'', dziggetai or simply ', mn, Хулан. Habitat and population The Mongolian wild ass has become primarily confined to the desert-steppe, semi-desert and deserts habitats of Gobi Desert. The Mongolian wild ass is the most widespread subspecies, although despite that, the subspecies lost about 50% of its former distribution ra ...
