Arctic

Fox

The arctic fox, also known as the white fox, polar fox or snow fox, is a small fox native to Arctic regions of the Northern Hemisphere and is common throughout the Arctic tundra biome. The Greek word alopex, means a fox and Vulpes is the Latin version. Lagopus is derived from Ancient Greek lago, meaning "hare", + pous, "foot" and refers to the hair on its feet. Although it has previously been assigned to its own genus Alopex, genetic evidence places it in Vulpes (Mammal Species of the World) with the majority of the other foxes.
