The Asiatic Wild Ass, also known as the Onager have never been domesticated.

They are among the fastest mammals, as they can run from 40 mph (64 km/h) up to 43 mph (70 km/h.) The onager is closely related to the African wild ass, as they both shared the same ancestor.

Five subspecies have been recognized, one of which is extinct.

The onager formerly had a wider range from southwest and central to northern Asian countries, such as Israel, Saudi Arabia, Iraq, Jordan, Syria, Afghanistan, Russia, and Siberia. During early 20th century, the species lost most of its ranges in the Middle East and Eastern Asia.

The onager lives in grasslands, plains, steppes, and savannahs.
