Both sexes have long shaggy hair with a dense woolly undercoat over the chest, flanks, and thighs to insulate them from the cold. Especially in bulls, this may form a long "skirt" that can reach the ground. The tail is long and horselike rather than tufted like the tails of cattle or bison. Domesticated yaks have a wide range of coat colours, with some individuals being white, grey, brown, roan or [[piebald]]. The [[udder]] in females and the [[scrotum]] in males are small and hairy, as protection against the cold. Females have four [[teat]]s.<ref name=Leslie2009/>
Yaks grunt and, unlike cattle, are not known to produce the characteristic bovine lowing (mooing) sound, which inspired the scientific name of the domestic yak variant, ''Bos grunniens'' (grunting bull). [[Nikolay Przhevalsky]] named the wild variant ''Bos mutus'' (silent bull), believing that it did not make a sound at all.<ref>{{Cite web|url=http://www.fao.org/docrep/006/AD347E/ad347e05.htm|title=ORIGINS, DOMESTICATION AND DISTRIBUTION OF YAK|last=|first=|date=|website=www.fao.org|access-date=2017-08-31}}</ref>
