Yaks are large, shaggy animals that live in the high mountains of Tibet and Mongolia. They are known for their thick fur, which keeps them warm in cold climates. Yaks are strong and can carry heavy loads, making them important for local people who rely on them for transportation and farming. These animals are also valuable for their milk, meat, and wool. Yak milk is often used to make delicious products like butter and cheese. Yaks are social creatures and usually live in herds, where they help each other stay safe from predators in their rugged environment.
