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] |
Persian Onager
The Persian onager (''Equus hemionus onager''), also called the Persian wild ass or Persian zebra, is a subspecies of onager (Asiatic wild ass) native to Iran (Persia). It is listed as Endangered, with no more than 600 individuals left in the wild and only 30 individuals living within North American institutions. Taxonomy and history The Persian onager is also simply named ' (گور) meaning "zebra" in Persian. "Onager" is from the Greek ''ὄναγρος'' (onagros), meaning "wild ass". Sometimes, the term "onager" is reserved specifically for this subspecies. However, as the whole species of the Asiatic wild ass is known simply as onager, it now also serves as the Persian wild ass's scientific name, as well (''Equus hemionus onager''). Information on the basic biology of the subspecies and how it differs from others is lacking, which hampers conservation efforts. Onagers used to be numerous from the Middle East to China. However, until the 19th century, their population has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turkmenian Kulan
The Turkmenian kulan (''Equus hemionus kulan''), also called Transcaspian wild ass, Turkmenistani onager or simply the ', is a subspecies of onager (Asiatic wild ass) native to Central Asia. It was declared Endangered in 2016. The species's population had recently been in decline in the country while it slowly increases in reintroduction sites. The Turkmenian kulan has been reintroduced to Kazakhstan and Uzbekistan, as well as Israel, where the subspecies are hybridizing with Persian onagers in the wild. Previously in 2005, the population was estimated at 1,295-1,345 in Turkmenistan. No other data existed on the condition of the Turkmenistan populations, but hope remained that small groups of animals still resided in inaccessible areas around Badkhyz, and were thriving in the West Kopetdagh (Sumbar-Chandyr Valley) and Ustyurt Plateau around Lake Sarakamish. However, certain fragmented populations of Transcaspian wild ass are currently on the rise to even more than 2,000 individua ...

Syrian Wild Ass
The Syrian wild ass (''Equus hemionus hemippus''), less commonly known as a hemippe, an achdari, or a Mesopotamian or Syrian onager, is an extinct subspecies of onager native to the Arabian peninsula and surrounding areas. It ranged across present-day Iraq, Palestine, Israel, Iran, Jordan, Saudi Arabia, Syria, and Turkey. Description The Syrian wild ass, one metre high at its shoulder, was the smallest equine, and it could not be domesticated. Its coloring changed with the seasons — a tawny olive coat for the summer months, and pale sandy yellow for the winter. It was known, like other onagers, to be untameable, and was compared to a thoroughbred horse for its beauty and strength. Distribution and habitat The Syrian wild ass lived in deserts, semi-deserts, arid grasslands, and mountain steppes. Native to West Asia, they were found in Israel, Palestine, Jordan, Turkey, Syria, Saudi Arabia, and Iraq. Ecology and behavior Diet The Syrian wild ass was a grazer and a browser. ...

Indian Wild Ass
The Indian wild ass (''Equus hemionus khur''), also called the Indian onager or, in the local Gujarati language, Ghudkhur and Khur, is a subspecies of the onager native to South Asia. It is currently listed as Near Threatened by IUCN. The previous census in 2009 estimated a population of 4,038 Indian wild asses. However, the population was still growing. In December 2014, the population was estimated at 4,451 individuals. As of 2015, the current Indian wild ass population has increased to around 4800 individuals in and outside of the Wild Ass Wildlife Sanctuary of India. The population has risen by 37% since 2014, reveals data released by the Gujarat forest department. The population has reached 6,082, according to the census conducted in March 2020. Physical description The Indian wild ass, as with most other Asian wild ass subspecies, is quite different from the African wild ass species. The coat is usually sandy, but varies from reddish grey, fawn, to pale chestnut. The an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fastest Animals
This is a list of the fastest animals in the world, by types of animal. Fastest organism The fastest land animal is the cheetah. The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom, with a diving speed of . Among the fastest animals in the sea is the black marlin, with uncertain and conflicting reports of recorded speeds. When drawing comparisons between different classes of animals, an alternative unit is sometimes used for organisms: ''body length per second''. On this basis the 'fastest' organism on earth, relative to its body length, is the Southern Californian mite, ''Paratarsotomus macropalpis'', which has a speed of 322 body lengths per second. The equivalent speed for a human, running as fast as this mite, would be . The speed of the ''P. macropalpis'' is far in excess of the previous record holder, the Australian tiger beetle '' Cicindela eburneola'', which is the fastest insect in the world relative to body size, with a reco ...

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 adapt ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

European Ass
The European wild ass (''Equus hemionus hydruntinus'') or hydruntine is an extinct equine from the Middle Pleistocene to Late Holocene of Western Eurasia. It appeared first in the fossil record around 350–300,000 years before present. In the late Pleistocene it was widespread throughout much of western Eurasia from the Middle East to Europe, especially along the Mediterranean, with fossil reports from Sicily, Turkey, Spain, France and Portugal. In the east the range apparently stretched at least to the Volga and to Iran. In the north it reached almost to the North Sea in Germany and the British Isles. Its range fragmented after the Last Glacial Maximum, surviving into the Holocene, its range gradually contracted further, persisting in small regions of southern Europe into the Bronze Age, and in Iran and the Caucasus into the Iron Age, around 500 BC. It has been suggested that the Iberian Zebro, extinct in the wild from the 16th century, could correspond to the ''Equus hydruntinu ...
