The Arctic Fox lives in some of the coldest areas on the planet. Their 'thick' body and shorter legs, ears and nose are all adaptations that decrease surface area exposed to the cold. They cover all of this with a thick coat that makes them look like a mobile snowball. In summer they are darker in color, which aids them in hunting small animals and sneaking up on nests to steal eggs. During the winter months they turn white and use their keen sense of hearing to locate prey under the snow.
