Equus hemionus hemionus, also known as the Asiatic Wild Ass or the Persian Onager, is a subspecies of the wild ass native to Iran, Turkmenistan, and possibly Afghanistan. The term Asiatic Wild Ass is sometimes used interchangeably with the subspecies name, as they refer to the same animal. Other common synonyms for Equus hemionus hemionus include the Persian Wild Ass, the Khur, and the Onager. The word "onager" actually comes from the Greek word for "wild ass." Despite their name, wild asses are not related to domestic donkeys and have a strikingly different appearance, with long legs and a sandy brown coat adapted to their desert environment.
