Detailed explanation-1: -Muskoxen are beautifully adapted to extreme arctic conditions. They live on open, unsheltered tundra, enduring shuddering gales, blowing snow and temperatures of –40 degrees or colder in the winter. One key to their hardiness is their extraordinary fur which consists of two layers.

Detailed explanation-2: -Muskox are native to Alaska, but were extirpated by the 1920s. In 1930, 34 muskox captured in East Greenland were transplanted to Alaska, and all muskox in Alaska today are descended from these animals.

Detailed explanation-3: -Musk oxen live in the frozen Arctic and roam the tundra in search of the roots, mosses, and lichens that sustain them. In winter, they use their hooves to dig through snow to graze on these plants. During the summer, they supplement their diet with Arctic flowers and grasses, often feeding near water.

Detailed explanation-4: -Musk ox (Ovibos moschatus): large, hoofed mammals in the Bovidae family. Musk oxen are members of the Bovidae family, which includes domestic cattle, sheep, goats, bison, antelopes, and wildebeest.
