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. [1] Domesticated species, such as the dogs formerly present, [2] are not ...
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.
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 (inside the inner line) and the Subantarctic zone (between the two lines) as defined in the WGSRPD The main article for this category is Fauna of Antarctica . This category is for articles about the native fauna of Antarctica .
West Antarctica, or Lesser Antarctica, one of the two major regions of Antarctica, is the part of that continent that lies within the Western Hemisphere, and includes the Antarctic Peninsula. It is separated from East Antarctica by the Transantarctic Mountains and is covered by the West Antarctic Ice Sheet .
A humpback whale, likely lured by a trawling net capturing masses of Antarctic krill, became entangled last month and died in the Southern Ocean. Scientists say the humpbacks may have been ...
