Episode Info

"Antarctica: The End of the Earth" concludes with a study of its icebergs ("haunting sculptures which hold the mysteries of life," says narrator Joseph Campanella) and the ecosystem they support. Plant life found on icebergs' undersides are eaten by shrimplike creatures called krill, which in turn are food for crabeater seals. Also seen feeding on iceberg feeding grounds: leopard seals; killer whales; Adelie and emperor penguins; and sea birds, including snow petrels. The hour also explores the effect of seasonal change on Antarctic wildlife.
