Life On The Edge

S1 E3: This is the story of an awe-inspiring coastline, 4000 miles long. From the cold, fearsome waters of Cape Horn - where brave rockhopper penguins overcome huge challenges to raise their young; to the far north, with huge elephant seals battling for position in the heat of the desert. Orcas ram-raid the beaches, grabbing seal pups to feed their young. People too gather the sea's bounty but these shores are not for the faint-hearted.
