Adaptations
Tundra animals special adaptations that help in extreme temperatures. Arctic foxes have short ears and a short, round body with a thick coat to minimize the amount of skin exposed to cold air.
A polar bear's white fur helps the animal hide in plain sight, they also have thick blubber and dense fur to keep them warm.
Caribou have developed many helpful adaptations for living in the tundra. They have large, fur-covered hooves for gripping the ice as the migrate across the frozen landscape. Their thick coats helps protect them from the cold weather.
