![]() ![]() It lives in miniature caves above the tide lines and uses its tail like a coiled spring to jump from rock to rock. Meanwhile, in the remote Pacific islands lives the most terrestrial fish on the planet. Desperate dads must escape the faster and more aerobatic skuas before finally delivering a meal to their young puffling. A father returns with one precious beakful of food. Puffins fly up to 30 miles out to sea to find food for their chicks. Over millennia these forces carve exquisite coastal sculptures and cliffs that are home to huge colonies of seabirds. Predatory starfish turn a magical garden into the stuff of nightmares.Īll around the world, immense waves pound the shore, and this episode reveals some of the largest on the planet, over 30 metres high. But these temporary worlds are a battleground. Elsewhere, the ever-changing tides create rock pools. Both crawl across dry rock to set their ambush. Moray eels launch themselves from rock pools, jaw gaping. Once trapped in the shallows, these huge fish are easy pickings.Īs the tide recedes in Brazil, lightfoot crabs leap from rock to rock, desperately avoiding the water - their lives depend on it. But here the sea lions club together to herd their prey inshore. It should be impossible - tuna are usually far too fast for sea lions to catch. In a secluded cove in the Galapagos, sea lions feast on 60kg tuna. We meet fish that live on dry land and puffins that must travel 60 miles or more for a single meal, and witness a life-and-death struggle in a technicolour rock pool. This episode is a rollercoaster ride of heart-stopping action and epic drama, peopled with characters from the beautiful to the bizarre. The extraordinary animals that live here must find ingenious ways to cope with two very different worlds. Coasts are the most dynamic and challenging habitats in the ocean - that brings great rewards but also great danger. Through these valiant efforts, theirs is now one of the densest leatherback nesting beaches in the world.On the coast, two worlds collide. ![]() Their numbers have dropped dramatically, by up to 90 per cent in some parts of the world, but here, volunteers are risking their lives to get turtle poachers to put down their weapons and instead protect the beach where these magnificent creatures nest. ![]() In the Caribbean, a community is reversing the fortune of giant leatherback turtles. He is using the latest technology to unlock one of the ocean's biggest mysteries - where these elusive giants may give birth. In the Galapagos, one scientist has devoted much of his life to saving the largest fish in the sea - the whale shark. Hundreds of giant humpback whales and one of the greatest gatherings of orcas on the planet feast on the herring - an extraordinary story of recovery.Īround the world, individuals are also making a huge difference to the future of the ocean. Today, thanks to careful regulation, they have returned, creating one of the greatest spectacles in the ocean. Every year, billions of herring overwinter in the icy seas off Norway, but just 50 years ago they were almost wiped out by overfishing. Yet, despite these devastating impacts, there is hope. We travel to Antarctica on a unique expedition to discover how melting polar ice sheets could one day impact the lives of hundreds of millions of people around the world. Warmer than normal seas caused the biggest coral bleaching event in human history, killing about 90 per cent of the branching corals at Lizard Island.īut the warming ocean could have an even more devastating effect. While filming the stunning corals on the Great Barrier Reef's remote Lizard Island, the film crew witnessed a catastrophe. Many creatures are struggling to survive in today's oceans, and some changes in the ocean will require a global effort. Scientists have even discovered that increasing noise levels may stop baby clownfish finding their way home. ![]() In this final episode, we uncover the impact that our modern lives are having on our best-loved characters from across the series, including devoted albatross parents unwittingly feeding their chicks discarded plastic and mother dolphins potentially exposing their newborn calves to pollutants through their contaminated milk. The oceans are changing faster and in more ways than at any point in human history and now, for the first time, we understand why. But we have also witnessed the profound effects of human activity. While making Blue Planet II, we have explored parts of the ocean that nobody has been to before, encountered extraordinary animals and discovered new insights into how life thrives beneath the waves. ![]()
