See National Geographic photos of Arctic animals. In times of plenty, each canid can cache up to a thousand goose eggs during the mating season, another unsung nutritional boost to the land—and opportunistic scavengers. With short ears and snout—which requires less energy to heat—as well as a heavily insulated coat, the species is perfectly adapted to winter, Person says.

The small proportion of this fax species which is the blue color phase in winter sheds its coat in spring to a thinner and darker bluish-gray in summer. The wide distribution of this fox in such a severe arctic environment is testament to its superb adaptation to cold and to the wide variety of food it will eat.

The compact body form, short snout and short, rounded, well-furred ears minimize heat loss from body extremities. The deep, thick pelage of very fine hair, and the hair on the soles of their feet provide excellent insulation.

Even in winter, arctic foxes seldom seek shelter during their incessant search for food, except during severe storms when they may dig a hole in a snow bank or search out a breeding den. The diet of the arctic fox is extremely varied throughout its range, related as it is to regional geographic characteristics and seasonal fluctuations in food supply.

Microtine rodents, such as lemmings, ground squirrels and voles are an important component of the diet. Foxes inhabiting marine regions also hunt for small marine animals, fish and carrion along shorelines. In winter, coastal arctic foxes venture onto the sea ice where they frequently trail polar bears to feed on the remains of seal kills.

Arctic foxes walk on top of the snow and use their acute hearing to listen for small creatures below. If they hear something move, they will jump up and down to break through the snow and reach with their front paws to grab the prey. Foxes living near water take advantage of access to marine animals like fish, seals, seabirds, and marine invertebrates.

THREATS: Arctic foxes are threatened by global warming, competition from the larger, northward-spreading red fox, and hunting and trapping for the fur trade. Some populations have suffered sharp declines due to over-hunting, including those in Scandinavia, where insufficient food sources in the s and s reduced fox numbers to an estimated adults.

As ice retreats and boreal forests spread northward, fox habitat shrinks, causing serious concern for the long-term survival of the species. Get the latest on our work for biodiversity and learn how to help in our free weekly e-newsletter.
