1. Ocean islands, their unique isolation has produced some of the most extraordinary, surprising, and unstable examples of life found nowhere else on Earth, from crabs that tear coconuts apart to carnivorous caterpillars that impale their prey on dagger-like claws. Human civilization is equally unique. On Pentecost Island, people leap from tall wooden scaffolding to celebrate their annual harvest, using jungle vines to prevent their fall. On the tiny island of Ifotaka, perhaps the most remote human society on Earth, the locals rely entirely on their crops and hunting for survival. 2. Drifters There are no true deserted islands in the South Pacific. They may be the most remote on Earth, but the 20,000-plus islands are all inhabited, from New Guinea, home of the bird of paradise, where tribal warriors undergo brutal initiation rites to become "crocodile men," to Fiji, French Polynesia, and Hawaii. This is the story of the last drifters, from saltwater crocodiles and giant eels to marine iguanas and strange frogs, who made desperate journeys across thousands of miles to reach these islands. These journeys were remarkable feats. It is estimated that only one species reaches Hawaii every 60,000 years. It is incredible that so many colonizers reached these islands, which have been repeatedly battered by nature's forces like hurricanes and tsunamis. The first human voyages in the South Pacific, by the Polynesians, are unforgettable. These journeys were indeed the greatest exploration ever, and it can be said that they permanently altered the natural landscape of the South Pacific. 3. Blue Desert Much of the ocean is remote, and the blue wilderness of the South Pacific is an oceanic desert. Many animals live in the ocean, including sharks, whales, and turtles, which must travel extraordinary distances to survive. Tiger sharks travel hundreds of miles to feast on fledgling albatross chicks, and every year, sperm whales travel from one side of the South Pacific to the other to feed and mate. Their journeys often end tragically. But the South Pacific is not all desert. New Zealand's super-rich coast supports large populations of dolphins, and its coral reefs are among the most diverse on Earth. Few places have as much wildlife as the bizarre Galápagos Islands, home to tropical penguins and surfing sea lions. The film is woven through with the greatest maritime disaster story—Moby Dick's inspiring event (Moby Dick). It reveals the immense survival challenges in what seems to be a vast blue ocean. 4. Ocean Volcanoes Witness the birth, growth, and death of islands in the largest ocean on Earth.Millions of years of history condensed into an hour, showcasing unforgettable images of underwater volcanic eruptions, with lava flows exploding beneath the waves. Roads and houses are buried by the lava flow. From the violent beginning, an incredibly rich coral reef emerges, nurturing large groups of grey nurse sharks and manta rays. The land rising in the South Pacific also brings life to some very strange animals, from bloodworms that thrive in tropical snow, to mound-building birds that rely on volcanic springs to incubate their eggs, to large groups of jellyfish trapped by coral reefs. 5. Strange Islands The isolated islands of the South Pacific are home to flightless parrots, bats that dig for food, large skinks, and tree-dwelling kangaroos. Wildlife evolves in strange ways. Surviving on an island may come at a high cost, and for new species, all want to escape this hell. This presents a puzzle: why do animals perfectly adapt to island life, easily giving up their freedom? The answer is revealed by certain unlikely animals living on a small island off the coast of New Zealand. Evidence from human history in the region further indicates that, regardless of its idyllic past, life on the South Pacific islands has never been far from disaster. 6. Fragile Paradise The South Pacific is still relatively healthy, with abundant fish, but it is a fragile paradise. International fishing vessels have sounded a serious alarm for sharks, albatrosses, and tuna, and there are other hidden dangers lurking in this beautiful sea. This episode focuses on how to preserve the ocean and its wildlife. Evidence from human history in the region suggests that the idyllic, thriving South Pacific has never been far from disaster.
