Episode THREE CORAL REEFS
CORAL REEFS COMPRISE 0.1 per cent of the ocean’s surface area but are home to a quarter of all marine species. We get to see a clownfish seeking the perfect nest and coral groupers who hunt with octopus. Using time-lapse, cameras also capture how coral grows and dies.
‘In Borneo, we see turtles relax while little fish pick off parasites and dead skin,’ says Attenborough. ‘One turtle sits back and shuts its eye while a little cleaner fish works over it to remove things. It’s like it is chilling out with a facial.’
