Antarctica is colder than the Arctic region, as much of Antarctica is over 3,000 m (9,800 ft) above sea level, where air temperatures are colder. The relative warmth of the Arctic Ocean is transferred through the Arctic sea ice and moderates temperatures in the Arctic region.
Marine mammals comprise over 130 living and recently extinct species in three taxonomic orders. The Society for Marine Mammalogy, an international scientific society, maintains a list of valid species and subspecies, most recently updated in October 2015. [1] This list follows the Society's taxonomy regarding and subspecies.
The citizen science scheme by WWF and British Antarctic Survey aims to help conserve walruses in the face of climate change.
There are also many different animals that live in the sea water near polar regions. Squids are one animal that live in both Antarctica and the Arctic. They are the food source for other large animals such as the male sperm whale. [21] There is also a wide variety of fish in the polar regions. Arctic cod is a major species in the Arctic.
