Musk Ox

The musk ox is a heavy-bodied Arctic mammal related to sheep and goats rather than a true ox. Long outer hair covers a fine insulating undercoat called qiviut. It feeds on grasses, sedges and other tundra plants, uncovering vegetation through snow when necessary. Herd members may form a defensive line or circle, with adults facing outward and calves sheltered closer to the center.
