The mammal living in the highest habitat--The Yak
Yaks, called Ya(k) in Tibetan and often termed the "Boat of the High Plateaux",are animals which live at the highest altitudes and are able to climb to a height of more than 6,100 metres.
Yaks are very long-haired bulky animals, mostly black, deep brown or piebald in colour. Thick-tailed, with their lower abdomen, legs and joints, shoulders and thighs covered with a thick mat of fur, they are very cold-resistant and never feel cold when lying asleep on the ice-cold ground and able to graze on the coarse fodder. With substantial, tough hoofs, they function as pack-animals to carry loads long distances across snow mountains or on the high plateau where the air is thin. The rich creamy milk of yaks has a high fat-content, and is often made into cheese and yak butter, necesities of Tibetan life. Yak beef is extremely high quality. yak fur can be made into cloaks, tents and ropes. The fine wool-like fur is prized quality material for the wool spinning industry .Yak -tails are an important export item.
Yaks are afraid of hot weather. hey are late maturing and generally start beraing young at four years. Originally from the mountainous regions of central Asia, in China the yak is distributed mainly in Qinghai, Tibet and adjacent cold regions where the altitude is more than 3,000 metres.
