''Asinus'' is a subgenus of ''Equus'' (single-toed (hooved) grazing animal) that encompasses several subspecies of Equidae commonly known as 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 are several never-domesticated species that live in Asia and Africa. == Taxonomy == * Genus: ''Equus'' * * Subgenus: ''Asinus'' * * * African wild ass, ''Equus africanus'' * * * * Nubian wild ass, ''Equus africanus africanus'' * * * * Somali wild ass, ''Equus africanus somaliensis'' * * * * Donkey, ''Equus africanus asinus'' * * * * Atlas wild ass, †''Equus africanus atlanticus'' (extinct) * * * Onager or Asiatic wild ass, ''Equus hemionus'' * * * * Mongolian wild ass or khulan, ''Equus hemionus hemionus'' * * * * Indian wild ass or khur, ''Equus hemionus khur'' * * * * Turkmenian kulan, ''Equus hemionus kulan''〔http://www.lhnet.org/kulan/〕 * * * * Persian onager or gur, ''Equus hemionus onager'' * * * * Syrian wild ass or hemippe, †''Equus hemionus hemippus'' (extinct) * * * Kiang or Tibetan wild ass, ''Equus kiang'' * * * * Western kiang, ''Equus kiang kiang'' * * * * Eastern kiang, ''Equus kiang holdereri'' * * * * Southern kiang, ''Equus kiang polyodon'' * * * * Northern kiang, ''Equus kiang chu'' * * * †''Equus calobatus'', Stilt-legged onager * * * †''Equus hydruntinus'', European ass * * * †''Equus tau'', Pygmy onager 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Asinus」の詳細全文を読む スポンサード リンク
