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 ...

At 2–6 mm (0.08–0.2 in) long, it is the largest purely terrestrial animal native to the continent. It also has the smallest known insect genome as of 2014, with only 99 million base pairs of nucleotides and about 13 500 genes. It is the only insect that can survive year-round in Antarctica.
