** 'THIS IS THE STORY OF OUR OCEAN AND WE MUST WRITE ITS NEXT CHAPTER TOGETHER. FOR IF WE SAVE THE SEA, WE SAVE OUR WORLD. AFTER A LIFETIME OF FILMING OUR PLANET, I'M SURE THAT NOTHING IS MORE IMPORTANT.'**

From the icy seas of our poles to remote coral islands, David Attenborough has filmed in every ocean habitat on planet earth. Now, with long-term collaborator Colin Butfield, he shares the story of our last great wilderness - the one which shapes the land we live on, regulates our climate and creates the air we breathe.

Dive into eight unique saltwater habitats, swim through kelp forests, mangroves and coral reefs and down almost 11,000 feet to the deepest corners of the most unexplored ecosystem on our planet.

Experience a journey of wonder and discovery, populated by green turtles and blue whales; clownfish and bioluminescent jellyfish; the vampire squid and the 'head-less chicken monster' - a strange form of sea cucumber that lives at the very bottom of the ocean.
