Good to know
Yaks live higher than almost any other large mammal, up to 6,000 metres.
Their lungs and heart are far bigger than a cow's, to get enough oxygen from thin air.
A woolly undercoat and long outer hair keep it warm at minus 40 degrees.
A yak begins to suffer from heat above about 15 degrees.
Yaks grunt. The tame yak's Latin name means grunting ox.
Tame yaks give Tibetan people milk, butter, wool, transport and even fuel: dried dung for the fire.
The real thing

Tame yaks are everywhere in Tibet, Nepal and Bhutan. Wild ones are bigger, darker and much rarer, on remote parts of the plateau.
Wild yaks are vulnerable. Large protected areas on the Tibetan plateau, such as Chang Tang, are what keep them going.
