Adult male yaks grow to an average height of two meters at the shoulder, and weight about 1000 kg and the females weight a third of that. A yak is covered with long and shaggy hair. It has a dense undercoat of soft, close matted hair. Wild yaks can be brown or black, and both males and females have horns.
