Dive into eight unique salt-water habitats, swim through kelp forests, mangroves and coral reefs and down almost 11,000 metres 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 'headless chicken monster' - a strange form of sea cucumber that lives at the very bottom of the ocean.

With the warmth, intelligence and awe that characterises all of David Attenborough's landmark series, Ocean shows us a world which is both desperately fragile yet astonishingly resilient, with an extraordinary capacity to repair itself. It's not too late to restore our most vital habitat. If we treat it with respect, our marine world will be even richer and more spectacular than we can imagine.

Award-winning broadcaster and natural historian David Attenborough and longtime collaborator Colin Butfield present a powerful call to action focused on our planet's oceans, exploring how critical this habitat is for the survival of humanity and the earth's future.

Through personal stories, history and cutting-edge science, Ocean uncovers the mystery, the wonder, and the frailty of the most unexplored habitat on our planet--the one which shapes the land we live on, regulates our climate, and creates the air we breathe. This book showcase the oceans' remarkable resilience: they can, and in some cases have, recovered the fastest, if we only give them the chance.

Drawing a course across David Attenborough's own lifetime, Ocean takes readers on an adventure-laden voyage through eight unique ocean habitats, countless intriguing species, and the most astounding discoveries of the last 100 years, to a future vision of a fully restored marine world--one even more spectacular than we could possibly hope for. Ocean reveals the past, present and potential future of our blue planet. It is a book almost a century in the making, but one that has never been more urgently needed.
