Description: The arctic fox lives in one of the most extreme enviroments on the planet . Among its adaptations for cold survival are a deep , thick fur a system with a countercurrent heat exchange circulation system to retain temperature within the paws . A high proportion of body fat along with a low surface area , with shorter muzzle legs , and ears that are thicker than their european counterparts . Since less of its surface area is exposed to the arctic cold , less heat escapes the body . Its furry paws allow it to walk on the ice . The arctic fox has such keen hearing that it can precisely locate prey under the snow . When prey is located , it leaps and punches through the snow to catch its victim . Its fur changes colour with the seasons : in the winter it is white to blend in with snow , while in the summer months it changes to brown .
