Sir David Attenborough is present a follow-up to the BBC’s 2001 aquatic nature series Blue Planet.
The veteran wildlife presenter will narrate the brand new seven-part landmark series – Blue Planet II – which will delve back into the sea to see some of the astonishing creatures living under water.
Sir David, 90, said: ‘I am truly thrilled to be joining this new exploration of the underwater worlds which cover most of our planet, yet are still its least known.’
The first Blue Planet generated nearly £20million is DVD and book sales and broadcast right.
This new series which has been four years in the making includes hairy-chested Hoff crabs, snub fin dolphins that spit water through the air, and a tool-using tusk fish.
The crew have also captured a dive with a sperm whale mother and calf, as she heads deep into the abyss to hunt.
Charlotte Moore, Director of BBC Content, said: ‘The BBC’s world renowned natural history unit are set to captivate audiences once again with unmissable stories of ocean life presented by the one and only David Attenborough – it really doesn’t get much better than that!’
Tom McDonald, Head of Commissioning, Natural History and Specialist Factual, said: ‘Blue Planet II promises to combine the exceptional craftsmanship that our audiences have come to expect from BBC Natural History with genuinely new revelations about the creatures and habitats of the world’s oceans.
‘I have no doubt it will thrill and delight the audience and deliver a new benchmark in Natural History film-making.’
