The yak has blackish brown hair that covers the entire body and tail. It also has large, curving horns.
The yak is designed with large lungs, a high red-blood cell count, and a high concentration of blood sugar. These features enable the yak able to survive in higher elevations. Many mountain-dwelling humans use the yak as a beast of burden since it can survive in such a demanding habitat.
