These dens have 4-8 entrances and a system of tunnels covering about 30 square meters. Habitat Found mainly in arctic and alpine tundra, usually in coastal areas. Negative In Iceland, the arctic fox is a threat to the sheep and lamb farming industry. The arctic fox has been driven out of some regions, such as northern Scandinavia, because of predators like the red fox. The arctic fox has been hunted by humans for its pelt, and also hunted in Iceland because of being a pest to sheep farmers.
Humans also keep arctic foxes in captivity in fur farms.
The fur of the arctic fox changes twice every year. The winter fur is entirely white, and the summer coat ranges from grey to brown on the back, to somewhat lighter on the belly. Mammals of the World. Johns Hopkins University Press, Baltimore Maryland. Burton M. and Burton R. 1980.
