What is the maximal age a Onager reaches?
An adult Onager (Equus hemionus) usually gets as old as 38.75 years.
Onagers are around 346 days in the womb of their mother. When born, they weight 40 kg (88.18 lbs) and measure 8 cm (0′ 4″). As a member of the Equidae family (genus: Equus), their offspring is 1 babies per pregnancy. Fully grown, they reach a bodylength of 2.25 meter (7′ 5″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The onager (; Equus hemionus), also known as hemione or Asiatic wild ass, is a species of the family Equidae (horse family) native to Asia. A member of the subgenus Asinus, the onager was described and given its binomial name by German zoologist Peter Simon Pallas in 1775. Five subspecies have been recognized, one of which is extinct.The Asiatic wild ass is larger than the African wild ass at about 290 kg (640 lb) and 2.1 m (6.9 ft) (head-body length). They are reddish-brown or yellowish-brown in color and have broad dorsal stripe on the middle of the back. Unlike most horses and donkeys, onagers have never been domesticated. They are among the fastest mammals, as they can run as fast as 64 km/h (40 mph) to 70 km/h (43 mph). The onager is closely related to the African wild ass, as they both shared the same ancestor. The kiang, formerly considered a subspecies of Equus hemionus, diverged from the Asiatic wild ass and has been acknowledged as a distinct species.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, the prehistoric European wild ass subspecies ranged through Europe until the Bronze age. During early 20th century, the species lost most of its ranges in the Middle East and Eastern Asia. Today, onagers live in deserts and other arid regions of Iran, Pakistan, India, and Mongolia, including in Central Asian hot and cold deserts of Kazakhstan, Uzbekistan, Turkmenistan, and China.Other than deserts, it lives in grasslands, plains, steppes, and savannahs. Like many other large grazing animals, the onager’s range has contracted greatly under the pressures of poaching and habitat loss. Previously listed as Endangered, onagers have been classified as Near Threatened by IUCN in 2015. Of the five subspecies, one is extinct, two are endangered, and two are near threatened (their status in China is not well known). Persian onagers are currently being reintroduced in the Middle East as replacements for the extinct Syrian wild ass in the Arabian Peninsula, Israel and Jordan.
