The Antarctic is a vast, icy continent at the very south of the planet. Terrestrial life in this cold, inhospitable environment is mainly confined to the few areas of exposed, ice-free rock; but in contrast, the oceans around the Antarctic support a rich marine ecosystem. Its waters, rich in nutrients and oxygen, support a wide variety of marine species, from tiny krill to a range of fish, seals, whales and seabirds.
