They are found in the far north of Canada, Alaska, Greenland, Norway, Siberia, and some Arctic islands.
Males are larger than females.
Both males and females have horns, but the male's horns are larger and extend across the animal's forehead. The musk ox has a massive, low-slung body, very long fur, a huge hump on the shoulders, and hoofed feet. Musk Oxen, like other ruminants, have a four-part stomach. Musk oxen travel in herds. The herd protects the young from predators, like wolves.
