The first fungi identified from the sub-antarctic islands was The desert surface is hostile to microscopic fungi due to large fluctuations in temperature on the surface of rocks, which range from 2 °C below the air temperature in the winter to 20 °C above air temperature in the summer. The large animals often migrate between the two, and smaller animals are expected to be able to spread via underwater currents.Antarctica's cold deserts have some of the least diverse fauna in the world. The large animals often migrate between the two, and smaller animals are expected to be able to spread via underwater currents. Most communities consist of only a few species. However, among smaller marine animals generally assumed to be the same in the Antarctica and the Arctic, more detailed studies of each population have often—but not always—revealed differences, show… 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 most studied community occurs in sandstone, and different species arrange themselves in bands at different depths from the rock surface. The rocky shores of mainland Antarctica and its offshore islands provide nesting space for over 100 million birds every spring. However, the more stable nanoenvironments inside the rocks allow microbial populations to develop. Microscopic fungi, especially Bacteria have been revived from Antarctic snow hundreds of years old.Other algae live in or on the sea ice, often on its underside, or on the Human activity poses significant risk for Antarctic wildlife, causing problems such as pollution, habitat destruction, and wildlife disturbance.
Flying birds nest on the milder shores of the Peninsula and the subantarctic islands.

Micro-arthropods are restricted to areas with vegetation and nutrients provided by the presence of vertebrates,Many terrestrial earthworms and molluscs, along with micro-invertebrates, such as Many benthic crustaceans have a non-seasonal breeding cycle, and some raise their eggs and young in a Crabs have traditionally not been recognized as part of the fauna in the Antarctic region, but studies in the last few decades have found a few species (mostly Several species of marine worms are found in the Southern Ocean, including Like several other marine species of the region, Antarctic The non-lichenised species come from 416 different genera, representing all major fungi phyla. Some islands are in addition protected through obtaining the status of a These problems are especially acute around research stations.Due to the historical isolation of Antarctic wildlife, they are easily outcompeted and threatened by Subantarctic islands fall under the jurisdiction of national governments, with environmental regulation following the laws of those countries. There is relatively little diversity in Antarctica compared to much of the rest of the world. Eight species of Around 98% of continental Antarctica is covered in ice up to 4.7 kilometres (2.9 mi) thick.The dry interior of the continent is climatically different from the western 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.
Terrestrial life is concentrated in areas near the coast. These nesters include species of Compared to other major oceans, there are few fish species in few Cod icefish (Nototheniidae), as well as several other families, are part of the The four species that inhabit sea ice are thought to make up 50% of the total biomass of the world's seals.The mainland of Antarctica has no macro-arthropods.
