The animals that do exist in the polar region are similar between the Antarctic and Arctic regions. The animals do differ by the temperature. In the Arctic some invertebrates include spiders, mites, mosquitoes and flies. In warmer areas of the polar regions moths, butterflies and beetles can be found.
A polar bear and its cub. Animals that are active in the winter have adaptations for surviving the intense cold. [55] A common example is the presence of strikingly large feet in proportion to body weight. These act like snowshoes and can be found on animals like the snowshoe hare and caribou.
The polar seas contain a huge biome with many organisms. Among the species that inhabit various polar seas and surrounding land areas are polar bear, reindeer (caribou), muskox, wolverine, ermine, lemming, Arctic hare, Arctic ground squirrel, whale, harp seal, and walrus. [1] These species have unique adaptations to the extreme conditions.
The Arctic fox (Vulpes lagopus), also known as the white fox, polar fox, or snow fox, is a small species of fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. [1] [8] [9] [10] It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as ...
Polar and deep-sea gigantism, where invertebrates are considerably larger than their warmer-water relatives, is common in this habitat. [ 6 ] [ 15 ] [ 16 ] These two similar types of gigantism are believed to be related to the cold water, which can contain high levels of oxygen, combined with the low metabolic rates ("slow life") of animals ...
The few animals that live on the mainland are birds such as Antarctic terns, grey-headed albatross, imperial shag, snowy sheathbill and the most well known inhabitant of Antarctica, penguins. The inhospitable environment helps to deter predators ; the few predators that hunt on the mainland, including the south polar skua and the southern giant ...

The region has an abundance of wildlife that has adapted to its intense conditions, ranging from large mammals such as polar bears and muskox, to small birds, and various species of plants. [6] Marine life includes walrus, seals, fish and microscopic ocean organisms such as algae and plankton. [6]
