The musk ox lives mostly in Arctic Canada and Greenland, and it feeds on the roots and mosses of the tundra. In the winter, when snow and ice cover the earth, musk oxen use their hooves to dig for food.
A thick coat of long, shaggy hair covers almost their entire body for insulation from the cold. Fortunately for them, when summer rolls around, musk oxen shed their warm undercoat.
