The arctic fox (Alopax lagopus) is a member of the canid family and is related to other foxes (such as the red fox species of the Denali area,) and wolves and dogs . polar bears, ermine and ptarmigan all similarly benefit from their winter white . The arctic fox is an incredibly hardy animal that can survive frigid Arctic temperatures as Spotlighting foxes, wolves, hares, owls, and even a polar bear , these. The Arctic fox is related to wolves, dogs and other foxes because they are all members of the Their main enemies are wolves, polar bears and humans.

They are the only subspecies of caribou to undergo such a change. Other subspecies remain brown or gray year-round, though the shades may lighten slightly with the growth of their winter coats. Peary caribou are the smallest subspecies of caribou and, because of their morphological differences, were once considered a separate species.

They belong to a different genus than true lemmings, which remain brown.

Strangely, they spend most of their time burrowing beneath the snow, which would seem to render camouflage unnecessary.

They even grow special winter claws—really extensions of the toe pads—for digging through the drifts to create nests and reach the stems of the Arctic willows upon which they feed.

Their skins were once used by Eskimo peoples as clothing embellishments. Ptarmigans willow ptarmiganWillow ptarmigan Lagopus lagopus.

They spend spring and fall in a mottled state, matching the patchy snow cover. The white-tailed ptarmigan Lagopus leucura turns entirely white, while the willow ptarmigan L. Ptarmigans even develop white boots to match; the downy foot covering also helps them to walk atop the snow. The air bubbles in their winter feathers—which may help with insulation—scatter light, making them appear more brightly white than other white birds.

Shelter quality is more important to the Arctic fox than the proximity of spring prey to a den.

Litters may contain as many as 25 the largest litter size in the order Carnivora. When predators and prey are abundant, Arctic foxes are more likely to be promiscuous exhibited in both males and females and display more complex social structures. Larger packs of foxes consisting of breeding or non-breeding males or females can guard a single territory more proficiently to increase pup survival. When resources are scarce, competition increases and the number of foxes in a territory decreases.

On the coasts of Svalbard, the frequency of complex social structures is larger than inland foxes that remain monogamous due to food availability. In Scandinavia, there are more complex social structures compared to other populations due to the presence of the red fox. Also, conservationists are supplying the declining population with supplemental food. One unique case, however, is Iceland where monogamy is the most prevalent. The older offspring 1-year-olds often remain within their parent's territory even though predators are absent and there are fewer resources, which may indicate kin selection in the fox.

They scavenge on carcasses left by larger predators such as wolves and polar bearsand in times of scarcity even eat their feces. In areas where they are present, lemmings are their most common prey, [16] and a family of foxes can eat dozens of lemmings each day.

In some locations in northern Canada, a high seasonal abundance of migrating birds that breed in the area may provide an important food source. On the coast of Iceland and other islands, their diet consists predominantly of birds. During April and May, the Arctic fox also preys on ringed seal pups when the young animals are confined to a snow den and are relatively helpless.

They also consume berries and seaweed, so they may be considered omnivores. Red Fox Successful in habitats as varied as forests and major cities, climate change has assisted the Red Fox to expand its range North and allow them to move much further into the territory of the Arctic Fox where it gives unwanted competition in an area where food is scarce at some times of the year.

There are even accounts of Red Foxes killing the much smaller and more specialised Arctic Foxes that are living within their territory. The Red Fox also appears in the dark colour phase, the silver fox, and a mixture where the red fox has a cross of dark fur along the back and across the shoulders this is known as a Cross Fox. Wolf The Arctic Wolf is a gray wolf that has adapted to conditions in the Arctic, they are white, have smaller ears and shorter muzzles. It is often thought of as a solitary animal but they are a pack animal that needs to range widely to find enough food.

Wolves are highly intelligent and work as a coordinated team to bring down caribou and musk oxen. Unlike the big cats, wolves are unable to kill their prey outright and will eat the prey animal alive until it dies from blood loss or shock. The packs that feed on migratory caribou will follow their food source as it migrates but the wolves of the Canadian Islands that eat Peary Caribou and Musk oxenstay in the north during the winter.

Failure of the prey animal can mean extreme hardship and death for these wolves on the edge.
