This is an Arctic Fox – a gorgeous animal that inhabits the Arctic tundra biome – with some of the most frigid conditions on the planet. They have wonderful adaptations to the cold: thick white fur (in the winter – brown in the summer), a countercurrent
heat exchange that keeps its paws warm on the snow & ice, and a small muzzle & ears to minimize heat loss. When resting it will wrap its thick tail over its head to prevent heat loss too.
Their favorite prey is lemmings, and they can eat a dozen or more a day. They also steal scraps from polar bear kills.
They seems to be a bit smaller that red foxes – and shorter, but with thicker coats.All arctic foxes in this gallery are captive.
