Imagine Dinosaurs's video: Endangered Wild Horses

The Somali wild ass is one of three subspecies (types) of African wild ass. Overall, the species is the smallest of the wild equids (horses, asses, and zebras). A typical African wild ass stands about four feet at the shoulder and weighs about 600 pounds. The kiang is the largest of the Asinus subgenus. It is native to the Tibetan Plateau, where it inhabits montane and alpine grasslands. Its current range is restricted to plains of the Tibetan plateau and Ladakh, India, and northern Nepal along the Tibetan border. The Mongolian wild ass (Equus hemionus hemionus), also known as Mongolian khulan, is the nominate subspecies of the onager. It is found in southern Mongolia and northern China. It was previously found in eastern Kazakhstan and southern Siberia before being extirpated there through hunting. Grevy's zebra. The largest of the zebra species, Grevy's zebra have thicker stripes and bigger ears than other zebras. They are also the most threatened: fewer than 2,500 Grevy's zebras may remain in the wild. Przewalski's horses, critically endangered horses found in Mongolia, are the last truly wild horse. Once thought to be the ancestor to the domestic horse, they are actually distant cousins. Mitochondrial DNA suggests that they diverged from a common ancestor 500,000 years ago.
