Can you believe they are related to Goats?

The muskox (Ovibos moschatus) is an Arctic mammal of the Bovidae family, 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 live primarily in Arctic North America, with small reintroduced populations in Sweden, Siberia and Norway.

As members of the subfamily Caprinae of the family Bovidae, muskoxen are more closely related to sheep and goats than to oxen, but are in their own genus, Ovibos. Both sexes have long curved horns. Muskoxen stand 1.2 m (3 ft 11.2 in) high at the shoulder on average, with females measuring 135 to 200 cm (53.1 to 78.7 in) in length, and males 200 to 250 cm (78.7 to 98.4 in). Adults, on average, weigh 285 kg (628 lb) and range from 180 to 400 kg (397 to 882 lb). The thick coat and large head often suggests a larger animal than the muskox truly is, but overfed zoo specimens have weighed up to 650 kg (1430 lbs). Their coat, a mix of black, gray, and brown, includes long guard hairs that almost reach the ground. Rare "white muskox" have been spotted in the Queen Maud Gulf Bird Sanctuary.Muskoxen can be domesticated and yield excellent meat, milk and wool. The wool, qiviut, is highly prized for its softness, length, and insulation value. Prices for yarn range between $40 and $80 per ounce (28 g).

Muskoxen are social and live in herds, usually of around 10–20 animals, but sometimes over 70. Winter herds consist of adults of both sexes as well as young animals. During the mating season, which peaks in mid-August, males compete for dominance, and one dominant bull drives other adult males out of the group. Non-breeding males will often form male only herds of 3-10 or wander the tundra alone. During this period all males are extremely aggressive. Bulls will even charge birds if they are close by.

The muskox, or its ancestor, is believed to have migrated to North America between 200,000 and 90,000 years ago, during the Pleistocene period, when it was a contemporary of the woolly mammoth. It is thought that the muskox was able to survive the last ice age (Wisconsin glaciation) by finding ice-free areas away from prehistoric peoples. The muskox gradually moved across North America and arrived in Greenland during the late Holocene.Muskoxen have a distinctive defensive behavior: when the herd is threatened, the bulls and cows will face outward to form a stationary ring or semicircle around the calves. This is an effective defense against predators such as wolves, but makes them an easy target for human hunters. Besides wolves and humans, the only natural predators of muskoxen are the grizzly (brown) bear and polar bear.
