Argali

The argali, or the mountain sheep (species Ovis ammon) is a wild sheep, which roams the highlands of Central Asia (Himalaya, Tibet, Altay). It is also the biggest wild sheep, standing as high as and weighing as much as . The Pamir argali (also called Marco Polo sheep, for they were first described by that traveller) may attain more than in length.

The general colouration varies between each animal, from a lightish yellow to a dark grey-brown. The face is lighter. Males have a whitish neck ruff and a dorsal crest. Males have two large corkscrew horns, some measuring in length. Males use their horns for competing with one another. Females also carry horns, but much smaller.

Argalis live in herds between 2 and 100 animals, segregated by sex, except during breeding season. Migrating herds, especially males, have been reported. With long legs, herds can travel quickly from place to place. Argalis tend to live at higher elevations during the summer.

Argalis are considered an endangered or threatened species throughout their entire range, due to habitat loss from overgrazing of domestic sheep and hunting. They are hunted for both their meat and their horns, used in traditional Chinese medicine.

Some sources classify mouflon as Ovis ammon musimon. However, DNA testing has not supported this. Several subspecies of argali have been genetically tested for mtDNA and one study found that the subspecies Ovis ammon ammon, O. ammon darwini and the urial subspecies, O. vignei bochariensis grouped closely while the subspecies Ovis ammon collium and O. ammon nigrimontana grouped with the urial subspecies O. vignei arkal.
