The Arctic Fox is the only native land mammal to Iceland. It came to Iceland at the end of the last ice age, walking over the frozen sea.
The Arctic Fox has a circumpolar range, meaning that it is found throughout the entire Arctic, including the outer edges of Greenland, Russia, Canada, Alaska, and Svalbard, as well as in Subarctic and alpine areas, such as Iceland and mainland alpine Scandinavia.
