Wild mammals in Iceland include the Arctic Fox, rabbits and reindeer. Polar bears occasionally visit the island, traveling on icebergs from Greenland. Icelandic waters are rich with marine life, including seals, whales, dolphins and over three hundred species of fish. The Arctic fox, also known as the white fox, polar fox, or snow fox, is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage.
The only native land mammal on Iceland is the Arctic fox. Walruses were native to Iceland, but disappeared after human settlement, likely as a result of hunting, climate change and/or volcanism. Animals that have been introduced include the American mink, which escaped from fur farms and prospered, and the reindeer.
