The Tibetan antelope, or ‘chiru', is well known for possessing the finest and warmest wool in the animal kingdom. This adaptation provides warmth in the harsh climate of the Tibetan plateau but has contributed greatly to this species' decline (2). These antelope are most closely related to wild sheep and goats, they have grey to reddish-brown coats with a remarkably soft and dense undercoat (2). The underparts are creamy white in colour and the bulbous nostrils have small inflatable sacs on the side (4). Male Tibetan antelope have slender, black horns that may reach 60 centimetres in length; in winter they possess black markings on the face and legs (2).
