The arctic fox is the only species in its genus although they are related to other foxes, wolves and dogs. They are particularly well adapted to the cold habitat that they live in with small, compact bodies that conserve body heat and thick, dense winter fur.
The winter coat is white-blue which camouflages the arctic fox against the snow and helps them to creep up on its prey. In the summer the coat is a light brown-grey and less thick.
The Arctic fox has small, rounded, furry ears which also helps them to conserve heat. They also have thick hair on their feet which insulates them against the cold Arctic snow.
