Many tundra animals have white or light brown coats to help them blend into the winter landscape. Tundra mammals have thick coats, and many have a double coat. This means they have both a thick fluffy undercoat to trap warm air near the body and long slick outer hairs that help water and snow slide off the body.
Tundra animals also expose as little skin as possible. Mammals typically expose the most skin around their muzzles and ears and sometimes around their paws. Some tundra animals have a thick layer of blubber to help insulate them from the cold.
Behavioral adaptations are also important characteristics of tundra animals. Arctic hares and musk oxen are famous for huddling together in large groups to help share body heat.
