The musk ox is a large, shaggy herbivore native to the Arctic regions of North America and Greenland. It has a thick coat of long hair that helps it survive in extremely cold temperatures. Musk oxen are known for their strong, curved horns, which can grow up to 3 feet long. They typically live in herds and are social animals, often forming strong bonds with one another. Musk oxen primarily graze on grasses, mosses, and other vegetation found in tundra ecosystems. They are well-adapted to their harsh environment, using their thick fur and fat layers for insulation. Despite their size and strength, musk oxen are vulnerable to predators like wolves and grizzly bears.
