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 ...

David Senchina notes that Hooker was the first botanist to set foot on Antarctica, in 1840; the first sighting of a plant on the continent was only a few years earlier, namely A. Young's observation of Deschampsia antarctica (Antarctic hair grass) in 1819, from HMS Andromache, and the first plant specimen from an Antarctic island had been ...
A half-mile of ice isn't enough to suffocate life. A team of scientists who drilled into one of Antarctica's subglacial lakes last year says the lake is pretty well-packed with living things. The ...
Antarctica's two flowering plant species, the Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis), are found on the northern and western parts of the Antarctic Peninsula. Antarctica is also home to a diversity of animal life, including penguins, seals, and whales.
For the purposes of this category, "Antarctica" is defined as the only area within the WGSRPD region of the "Antarctic Continent" in the Antarctic botanical continent, according to the WGSRPD. This region includes only the mainland of Antarctica and immediately adjacent islands.
