'''''[[Usnea antarctica]]''''' is a shrub [[lichen]] found throughout the continent of [[Antarctica]] as well as on Subantarctic islands. This species of lichen is the [[National Symbols of Westarctica|national plant]] of [[Westarctica]]. It predominantly grows on exposed rock and can even be found growing on different sides of individual pebbles. ''U. antarctica'' has an extremely slow growth period and are among some of the longest-lived species on planet earth. An age of 200 years is typical for most specimens, however, the record age for ''U. antarctica'' is an estimated 4,500 years. In the Antarctic, its tendrils grow to a width of a few millimeters, while in the Subantarctic, they can grow to be over a foot in length. Specimens are plentiful at the abandoned [[Russkaya Station]] on the [[Ruppert Coast]] and have been studied as part of a research effort surrounding the soils of [[Marie Byrd Land]].
The '''[[Orca]]''' is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as there is no animal that preys on them. Killer whales are considered a cosmopolitan species, and can be found in each of the world's oceans in a variety of marine environments, from Arctic and [[Antarctica|Antarctic]] regions to tropical seas.
