Antarctica is one of the most physically and chemically extreme terrestrial environments to be inhabited by lifeforms. [1] The largest plants are mosses, and the largest animals that do not leave the continent are a few species of insects. Microbiome on the High Antarctic Plateau
Nothofagus fusca, New Zealand. Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana.Presently, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia.
In Antarctica there is not a lot of diversity among the fish; there is a lot of the same kind. Antarctic silverfish and lanternfish are some examples of fish that live in Antarctica. [22] Seals are also found in polar regions and number around 2.5 million. [23] They are known to breed on land in the polar regions.
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
Antarctic krill (Euphausia superba) are a keystone species, forming an important part of the Antarctic food web.. 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.
For example, in 2013 W. H. Walton in his Antarctica: Global Science from a Frozen Continent describes it as "a major reference to this day", encompassing as it does "all the plants he found both in the Antarctic and on the sub-Antarctic islands", surviving better than Ross's deep-sea soundings which were made with "inadequate equipment".

Humans can make or change abiotic factors in a species' environment. For instance, fertilizers can affect a snail's habitat, or the greenhouse gases which humans utilize can change marine pH levels. Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and ...
A five-month-long slumber party. A college dorm. An introvert’s hell. Those are just some of the words residents of Antarctica use to describe life in the world’s coldest, most mysterious ...
