Seven Worlds, One Planet: Episode 1
Antarctica, a land of survivors enduring the most hostile conditions on Earth. Ninety eight per cent of the mainland is covered by ice on which virtually nothing can live. Even the sea freezes over, but the Weddell seal manages to survive here by keeping its breathing holes open by using its teeth to grind away the ice.
