The Musk Ox (Ovibos moschatus) is one of only a few large mammals to have survived the Pleistocene extinctions. With it’s double layered coat of fur, and the ability to slow its metabolic rate by reducing both oxygen intake and CO2 production, the musk ox is uniquely suited to survive the harshest of winters. Musk Ox are herd animals with a highly developed social structure. When attacked, they are known to surround their young, elderly, or infirm members, facing horns outward in a protective circle. Hopefully these amazing animals will be able to survive in a warming world.
