Antarctica—the coldest, windiest, most hostile continent. Only the toughest can survive here. From Weddell seals that grind back the ice with their teeth, to colourful starfish carpeting the seabed beneath the ice. Huge colonies of king penguins crowd any ice-free land, and four tonne elephant seals fight for territory on the beach. Life comes here because the ocean that surrounds the continent is incredibly rich. However, the ocean here is warming and with that comes an uncertain future. Grey-headed albatross chicks battle for survival in the harsh gales of South Georgia, while southern right whales slowly recover from almost total annihilation at the hands of the whaling industry, and Gentoo penguins face a dangerous trek across uneven ice where leopard seals dwell. There is still hope for this ice-bound continent; thousands of penguins, seals, albatross, and over a hundred great whales feast on krill baitballs, whilst below the ice on the sea floor, an entire ecosystem of sea anemones, starfish, nudibranches, jellyfish and giant nematode worms live out their lives in the icy depths.
