The arctic fox lives in some of the most frigid extremes on the planet. This fox has several adaptions including its deep, thick fur, a system of countercurrent heat exchange in the circulation of paws to retain core temperature, and a good supply of body fat. The arctic fox has short muzzle and legs, and short, thick ears. Very little surface area on this fox is exposed to the cold, so very little heat escapes the body. Another adaption for this animal would be it's furry paws. They allow it to walk on ice in search of food. The arctic fox's hearing allows it to hear prey underneath the snow. When it finds prey, it pounces and punches through the snow to catch its victim. Its fur changes color with the seasons: in the winter it is white to blend in with snow, while in the summer months it changes to brown.
