Todays barren Antarctic landscape little resembles ancient Paleozoic and Mesozoic ones with their far greater floral displays. The importance of such microclimates was demonstrated by the second Byrd Antarctic Expedition (193335), which found that lichens in Marie Byrd Land grow preferentially on darker-coloured heat-absorbing rock.

There are no herbivores on the Antarctic continent, because Other penguin species, such as the King Penguin and the Rockhopper Penguin, are also found on subantarctic islands near Antarctica. The amount of energy any animal or fish requires in such an inhospitable environment means that being a herbivore would make it impossible to exist. careers Diatoms, a type of algae, are especially abundant.
