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.
Although they are remote from human world, polar seas are not 'pristine' environments. Compared with the Antarctic region, the Arctic has long history of interaction with man. The polar food web structure can be sensitive to man's 'top-down' control especially with the development and growth of industrial fishing. Climate change is a natural ...
Polar regions receive less intense solar radiation than the other parts of Earth because the Sun's energy arrives at an oblique angle, spreading over a larger area, being less concentrated, and also travels a longer distance through the Earth's atmosphere in which it may be absorbed, scattered or reflected, which is the same thing that causes ...

[41] [42] Glyptonotus antarcticus at up to 20 cm (8 in) in length and 70 grams (2.5 oz) in weight, and Ceratoserolis trilobitoides at up to 8 cm (3.1 in) in length are unusually large benthic isopods and examples of Polar gigantism. [43] [44] Amphipods are abundant in soft sediments, eating a range of items, from algae to other animals. [6]
The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. [3] Arctic land is bordered by the subarctic.
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 McMurdo Dry Valleys region of Antarctica is a polar desert characterized by extremely low annual precipitation (<100 mm (3.9 in)) and an absence of vascular plants and vertebrates; microbial activity dominates biological functioning. [2]
