The wild yak is a large mammal with long, thick fur. It lives on the high plateaus of Central Asia and is perfectly adapted to cold, strong winds, and thin air.
The wild yak is larger and stronger than the domestic yak. Its thick fur and large lungs help it live high in the mountains. It is important for nature because it eats plants and helps maintain alpine meadows.
