The muskox (Ovibos moschatus, also spelled musk ox and musk-ox) is an Arctic mammal of the family Bovidae, noted for its thick coat and for the strong odor emitted by males, from which its name derives. This musky odor is used to attract females during mating season. Muskoxen primarily live in the Canadian Arctic and Greenland, with small introduced populations in Sweden, Siberia, Norway, and Alaska.
