The arctic fox lives in some of the most frigid extremes on the planet. It lives in Arctic regions of the Northern Hemisphere and is common throughout the Arctic tundra biome. he arctic fox has such keen hearing that it can precisely locate the position of prey under the snow. When it finds prey, it pounces and punches through the snow to catch its victim. Its fur changes colour with the seasons: in the winter it is white to blend in with snow, while in the summer it is brown.
