The arctic fox is the only land mammal native to Iceland, but it also can be found throughout the Arctic region: Scandinavia, Russia, Greenland, Canada, and Alaska.
Arctic foxes have two color variations. The white foxes, seen here, appear fully white in winter, but during the summer, they gain some brown coloration to their fur to better blend in with the landscape. The "blue" foxes are actually dark brown, but have a slightly blue tinge to their fur. The white fur gene is a recessive one, so while blue fox parents can have white kits, two white adults would not have blue babies.
