The following is a list of native wild mammal species recorded in Antarctica. There are 23 mammal species in Antarctica, all of which are marine. Three are considered endangered, one is vulnerable, eight are listed as data deficient, and one has not yet been evaluated. [1] Domesticated species, such as the dogs formerly present, [2] are not ...
At least 235 marine species are found in both Antarctica and the Arctic, ranging in size from whales and birds to small marine snails, sea cucumbers, and mud-dwelling worms. The large animals often migrate between the two, and smaller animals are expected to be able to spread via underwater currents. [8]
Adelie penguins in Antarctica. This is a list of the bird species recorded in Antarctica.The avifauna of Antarctica include a total of 63 species, of which 1 is endemic.This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 2022 edition.
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.
Walrus live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve molluscs. Walruses are relatively long-lived, social animals, and are considered to be a " keystone species " in the Arctic marine regions.
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.
Antarctic fur seals are member of the genus Arctocephalus.Recently, a proposal was made to reassign this species to the resurrected genus Arctophoca.. Antarctic fur seals may be confused with southern otariids that share their range, like Subantarctic (A. tropicalis), New Zealand (A. forsteri), and South American fur seals (A. australis), and the Juan Fernandez fur seal (A. phillippii), as ...
The Antarctic tern does not migrate like the Arctic tern does, but it can still be found on a very large range. This tern species is actually more closely related to the South American tern. [2] Gulls, skuas and jaegers are the primary predators of the bird's eggs and young. The Antarctic tern can be further divided into six subspecies.
