Musk oxen are large, shaggy mammals native to the Arctic regions of North America and Greenland. They are known for their thick fur, which helps them survive in extremely cold temperatures. Musk oxen have a distinctive appearance, with long curved horns and a robust body, making them well-adapted to their harsh environment. These animals are social and typically live in herds, which provide protection against predators. Musk oxen primarily graze on grasses, mosses, and other vegetation. Their unique adaptations and behaviors make them an important part of the Arctic ecosystem.
