For most people, hair is a decorative yet essentially unnecessary feature of their anatomy. But to most mammals in the wild, hair offers important protection from the elements. The musk ox is a superb example. It has an important adaptation to its bitterly cold home on the vast Alaskan tundra: Its thick, shaggy hair hangs down to the ground and gives the ox the protection it needs to endure frigid temperatures. Such fur helps the animal survive as winter temperatures drop to an average of -30°F. Some of the hair is shed in time for summer, allowing the musk ox to cool down as temperatures reach 40-50°F.
