Arctic foxes are powerful creatures, rather squat with long legs. They have a very pointed muzzle, narrow ears and a long, bushy tail. In winter the arctic fox has a white coat and in summer the colour changes to grey or brown. This gives it camouflage as well as providing protection from the cold, making it ideally suited for its environment. The soles of its feet are just as hairy as the rest of his body. This means that it can withstand icy temperatures on its long journeys unscathed. Arctic foxes live a maximum of 10 years.
