The thermal conductivity of Arctic fox fur in the summer and winter is the same; however, the thermal conductance of the Arctic fox in the winter is lower than the summer since fur thickness increases by 140%. In the summer, the thermal conductance of the Arctic foxes body is 114% higher than the winter, but their body core temperature is ...
Arctic fox fur is a type of fur obtained from the arctic fox (also known as the polar fox) and turned into a commodity. The arctic fox is zoologically divided into two color varieties, the white fox and the blue fox, whose fur is also a commodity as blue fox fur. The white fox, the color variety of the arctic fox, lives in the entire northern ...
The fur of the arctic fox (Vulpes lagopus) is currently the most popular of all the farmed fox species, particularly the blue fox (white with grey tips) and the shadow blue fox (all white). [21] The overwhelming popularity of this fox has to do with the size of the production of arctic fox pelts and the dyeable nature of the color lead it to ...
Arctic hare - In Newfoundland and southern Labrador, the Arctic hare changes its coat color, moulting and growing new fur, from brown or grey in the summer to white in the winter, like some other Arctic animals including ermine and ptarmigan, enabling it to remain camouflaged as the environment changes.

The arctic fox (Vulpes lagopus) and the stoat (Mustela erminea) have fur that changes from white and dense in the winter to brown and sparse in the summer. In pinnipeds and polar bears , a thick insulating layer of blubber helps maintain their body temperature.
An arctic fox walked more than 2,737 miles to go from northern Norway to Canada's far north in four months, Norwegian researchers said.
Seal pups are born with a white lanugo (fur coat) that is shed about a month after birth. These pups do not enter the water until their lanugo is completely gone because their layer of blubber, and protection from cold ocean temperatures, remains undeveloped until shedding. Young ribbon seals were over hunted because of their soft and dense fur ...
There are several types of polyphenism in animals, from having sex determined by the environment to the castes of honey bees and other social insects. Some polyphenisms are seasonal, as in some butterflies which have different patterns during the year, and some Arctic animals like the snowshoe hare and Arctic fox, which are white in winter ...
