The Tibetan antelope, (, Indian English "chiru") is also endangered. Early in the 20th century the "chiru" was seen in herds of thousands, surviving on remarkably sparse vegetation, but they are vanishingly rare now. It has been hunted for its fine under-wool (Urdu: "shahtoosh", ), which must be pulled out by hand, a process done after the animal is killed. This "shahtoosh" is valued in South Asia for its light weight and warmth, but more than anything else, as a status symbol. Owning or trading in "shahtoosh" is now illegal in most countries.
