Which of these animals is noted for its thick coat and for the strong odor?

The muskox ('Ovibos moschatus'), also spelled musk ox, is an Arctic hoofed mammal of the family Bovidae, noted for its thick coat and for the strong odor emitted during the seasonal rut by males, from which its name derives. This musky odor is used to attract females during mating season.

Muskoxen primarily live in Greenland and the Canadian Arctic of the Northwest Territories and Nunavut, with introduced populations in the American state of Alaska, the Canadian territory of Yukon, the Scandinavian Peninsula, and Siberia.

Muskoxen live in herds of 12–24 in the winter and 8–20 in the summer.

They do not hold territories, but they do mark their trails with preorbital glands. Male and female muskoxen both have separate age-based hierarchies, with mature oxen being dominant over juveniles. Dominant oxen tend to get access to the best resources and will displace subordinates from patches of grass during the winter. Muskox bulls assert their dominance in many different ways. One is a "rush and butt", in which a dominant bull rushes a subordinate from the side with its horns, and will warn the subordinate so it can have a chance to getaway.
