The Life of Animals | Muskox | Both sexes have long curved horns. Average adult weighs 285 kg (600 lb), and the range of 180-410 kg (400-900 lb). The thick and large head often suggests a larger animal musk oxen and really, bison, musk ox, which is regularly compared, can be up to twice as much. Rare 'white' musk oxen were found in the Queen Maud Gulf Bird Sanctuary. Musk oxen are sometimes domesticated for wool, meat and milk. Qiviut wool is valued for its softness, length and insulation value. Musk oxen are native to Arctic regions of Canada, Greenland and the United States. The species was introduced from Iceland Banks in northern Europe, including Sweden. The world population is estimated from 80,000 to 125,000, with an estimated 68,788 living on Banks Iceland. Muskox was successfully introduced in the Taimyr Peninsula in 1975 again.

Musk oxen ate grass pastures arctic woody plants, lichens and mosses. Muskoxen have a high threshold of fat reserves before design, reflecting their conservative breeding strategies. Dig winter camp in the snow surface to reduce total energy costs in the snow to reach food. Musk oxen live in herds that number 12-24 and 8-20 in winter and summer. Muskox have both male and female age hierarchies bills with oxen dominant mature minors. Dominant cattle guard, better access to resources and move subordinates tufts in winter. Muskox bulls assert their dominance in many ways. Shout Bulls swung his head and paws the ground. Tori dominant sometimes treat subordinate bulls like cows. A dominant male accidentally throws one of his subordinates with his foreleg, which are cows during mating.

Some organizations subordinate bull can change the charge state of a dominant male. Coupling (or "rutting") season begins muskox late June or early July. Fighting bulls rub first pre-orbital glands against their legs crying out loud, and then shows the horns of bulls and walk upwards of 20, lowered his head and charged into each other and continue to do so until that when a bull goes. But older people and bulls leave the herd form bachelor groups or become loners. Tori prevent dominant cows from their harems. Herds reassemble when the summer ends. Herds move more frequently when the cows get enough food to feed their children. Cows have a gestation period of 8-9 months with the birth occurring from April to June, cows do not give birth every year. At birth remain the cows in the herd protection. Then begins a calf occasionally eat the vegetation and nurses. Cows and their calves communicate bray.

Musk oxen have characteristic defensive behavior when the herd is threatened, the bulls and the cows are outwardly to form a stationary or semi-circle around the calves. The bulls are usually flock to the first line of defense against predators and cows and young people around. Bulls determine the defensive formation during rutting while the cows decide the rest of the year, Historically, this species has declined due to hunting, but population recovery took place after the implementation of the legislation on hunting. Most populations are in the National Park, where they appear to be protected against hunting muskox in four protected areas of Greenland, found with the indigenous peoples in northern Greenland National Park and three introduced populations in reserves Arnangarnup Qoorua Kangerlussuaq natural and and Manii
