Antarctic fish are best known for their uses in studying adaptive radiation, the ecological process that causes the rapid development of several different species from one common ancestor of this fishes. These studies have been done using genetics, phylogeny, study of paleontology, and combinations of these fields to determine the sister ...
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 Register of Antarctic Marine Species has 9,350 verified species (16,500 taxa) in 17 phyla, from microbes to whales. For 1500 species the DNA barcode is available. The information from CAML is a robust baseline against which future change may be measured.

The group is found mainly in Antarctic and Subantarctic waters, with some species ranging north to southern Australia and southern South America. [2] [3] Notothenioids constitute approximately 90% of the fish biomass in the continental shelf waters surrounding Antarctica. [4]
