What "Planet Earth" 9-th episode about
A humpback whale mother and calf embark on an epic journey from tropical coral paradises to storm ravaged polar seas.
Newly discovered coral reefs in Indonesia reveal head-butting pygmy seahorses, flashing 'electric' clams and bands of sea kraits, 30-strong, which hunt in packs. Elsewhere plagues of sea urchins fell forests of giant kelp. Huge bull fur seals attack king penguins, who despite their weight disadvantage, put up a spirited defence.
