Bos mutus (wild yak)

The yak (Bos grun­niens) is a wide­ly domes­ti­cat­ed long-haired bovine native to the Tibetan Plateau of Cen­tral Asia. Their phys­i­o­log­i­cal adap­ta­tions for life at high altidudes include enlarged lungs and hearts, a form of haemo­glo­bin with greater oxy­gen car­ry­ing capac­i­ty, thick fur, and a thick lay­er of sub­cu­ta­neous fat. Wild yak pop­u­la­tions (Bos mutus or Bos grun­niens mutus) are now restrict­ed to a few small regions in Chi­na and India.
