| Distribution of Wild yak | |
Most yaks are domestic, which means they live on farms run by people. There are a few wild yak but there are not many left and are in danger of extinction.[2] There may be as few as 100 yak left in the wild.[2] Wild male yaks stand about 2–2.2 meters tall at the shoulder, the females about 1 metre. Domestic Yaks are shorter, between 1 and 2 metres for both males and females.[2] All yaks have long, thick hair to keep them warm in the cold places they live. Wild yaks can be black or brown. Some domestic yaks are white.[3] All kinds of yaks have horns. The closest relatives of yaks are considered to be bison, which have historically been considered members of their own titular genus, rendering the genus Bos paraphyletic.
Life
Yaks are herd animals. This means they live in groups called herds. Yaks are herbivores, they don't eat meat. The oldest yaks can live up to 25 years.[2]
