The large animals often migrate between the two, and smaller animals are expected to be able to spread via underwater currents. [8] 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, showing that ...
Antarctic fur seals and southern elephant seals, in contrast, while doing much of their feeding at the edge of the continent, breed on subantarctic islands, such as South Georgia. Warmblooded prey makes up a significant proportion of the leopard seal's diet, and is occasionally taken by Antarctic fur seals. Suborder: Caniformia

Some species of marine animals exist and rely, directly or indirectly, on phytoplankton. Antarctic sea life includes penguins, blue whales, orcas, colossal squids and fur seals. [116] The Antarctic fur seal was very heavily hunted in the 18th and 19th centuries for its pelt by seal hunters from the United States and the United Kingdom. [117]
Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere , and it contains land and the islands that surrounds it.
Belgica antarctica, the Antarctic midge, is a species of flightless midge, endemic to the continent of Antarctica.At 2–6 mm (0.08–0.2 in) long, it is the largest purely terrestrial animal native to the continent.
Most of the interior of Antarctica is polar desert, despite the thick ice cover. Conversely, the McMurdo Dry Valleys of Antarctica, although they have had no ice for thousands of years due to katabatic wind but contain ephemeral streams and hypersaline lakes characteristic of extreme non-polar deserts, are not necessarily polar desert ...
Polar ecosystems are particularly sensitive to climate change, where small changes in temperature result in greater changes in local hydrology, dramatically affecting ecosystem processes. [ 3 ] Soils in Antarctica are nearly two-dimensional habitats, with most biological activity limited to the top four or five inches by the permanently frozen ...
