The wildlife of Antarctica are extremophiles, having adapted to the dryness, low temperatures, and high exposure common in Antarctica. The extreme weather of the interior contrasts to the relatively mild conditions on the Antarctic Peninsula and the subantarctic islands , which have warmer temperatures and more liquid water.
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.

A team of scientists who drilled into one of Antarctica's subglacial lakes last year says the lake is pretty well-packed with living things. ... life can survive under Antarctica's ice sheets, far ...
The cooling strengthens the polar vortex and so prevents the outflow of the cold air near the South Pole, which in turn cools the continental mass of the East Antarctic ice sheet. The peripheral areas of Antarctica, especially the Antarctic Peninsula, are then subjected to higher temperatures, which accelerate the melting of the ice. [104]
Antarctica was also part of the ancient supercontinent of Gondwanaland, which gradually broke up by continental drift starting 110 million years ago. The separation of South America from Antarctica 30–35 million years ago allowed the Antarctic Circumpolar Current to form, which isolated Antarctica climatically and caused it to become much colder.
The snowy sheathbill does not have webbed feet. It finds its food on land. It is an omnivore, a scavenger, and a kleptoparasite and will eat nearly anything. It steals regurgitated krill and fish from penguins when feeding their chicks and will eat their eggs and chicks if given the opportunity.
The fishing company, Norway's Aker BioMarine, said these were its first cases of whale bycatch in 15 years of harvesting krill in Antarctica, and that it has since reinforced its ships' devices ...
