Muskox

Muskox have a outer coat of dark guard hair to repel against rain and snow; as well as a fine, soft inner coat which is so dense that cold or frost cannot penetrate it.  Males have larger horns than females and also excrete a characteristic odor during rut. They are primarily grazers on low vegetation such as grasses, sedges and browse.

Muskox can live up to 24 years of age
