The muskox is a large mammal with very dense wool. It lives in the Arctic tundra and uses its horns for protection from predators and fighting other males.
The muskox differs from other ungulates with its very dense undercoat and the way it protects the entire herd in a circle with horns outward. It is important for the tundra because it serves as food for wolves and helps preserve the plant cover.
