There are two types of Yak: domestic and wild. Domestic Yaks are smaller, have a less shaggy coat, and probably originated from wild Tibetan Yak. Domestic Yaks are used for travel and as draft animals. Yaks are valuable for their milk, meat, wool, and dung. The wild Yak is threatened by loss of habitat and over hunting. Their current status is “vulnerable.” The male wild Yak can weigh up to 2200 pounds and is 6.5 feet high at the shoulder.

10. Yaks have a cleft or split hoof, which makes them agile over rocky or icy ground.
11. Yaks possess great lung capacity so they can absorb more oxygen. Their digestive system is also designed to keep them warm.
12. In winter a wild Yak can survive temperatures as low as - 40 degrees (F).
13. A wild Yak reaches its full size between 6 to 8 years.
