Arctic foxes are incredibly hardy animals that can survive brutal freezing temperatures as low as -50C (-58F). The animals have furry-soled paws, short ears and a short muzzle to help them manage cold climates.

In winter food for the fox is scarce and they often follow larger predators, like polar bears, to eat their leftovers. They live on average for three to six years in the wild and weigh up to 7.5kg (17 lbs).

The ultimate fate of the fox is unknown – the GPS tracker stopped working in February this year.
