London,Oct07:BBC has released an astonishing new trailer for Blue Planet II, a follow-up to the groundbreaking nature documentary which was first screened 16 years ago.
Film crews have spent four years diving deep into the oceans to film some of the world’s strangest and most beautiful sea creatures.
Renowned naturalist Sir David Attenborough will be presenting the series.
Sir David turned 90 last year and had been rumoured to have been on the verge of retirement.
But his involvement in Blue Planet II is being seen as a coup for the BBC.
He 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 new trailer follows a previous clip featuring music by Radiohead and the Hollywood composing legend Hans Zimmer.
The new series of Blue Planet II was announced back in February and will air on October 29.
When the first series aired in 2001, it received widespread acclaim from the public and critics alike.
It also made nearly £20 million in the sales of DVDs, books and broadcast rights, while the show was sold to more than 150 territories across the globe.
The new series will feature creatures which have never been caught on film before, including the Hoff Crab, which is named after Baywatch star, David Hasselhoff.
Other sea beasties include snubfin dolphins that spit water through the air and a tusk fish, which is shown using tools.
Coral groupers, reef octopus and giant trevally fish will also star in the show.
New specially-developed camera technology allowed the crew to film predators front-on, and even “travel” on the backs of whales, sharks and orcas.
One scene will show a sperm whale mother and her young calf as they head deep into the abyss to hunt prey.
Camera crews travelled to every continent and worked across every ocean to film scenes for the new documentary.
The series is set to show both icy polar seas, vibrant coral atolls and the storm-beaten Atlantic coastline.
Viewers will also be shown new landscapes such as methane volcanoes which erupt in the Gulf of Mexico and the so-called boiling sea phenomenon in the Pacific Ocean.
For the first time, the show will also show footage of the Antarctic at 1000 metres deep after taking two manned submersibles to explore the polar ice cap.
Executive Producer James Honeyborne said: “The oceans are the most exciting place to be right now, because new scientific discoveries have given us a new perspective of life beneath the waves.
“It will provide a timely reminder that this is a critical moment for the health of the world’s oceans.”
