Groundbreaking documentary which follows a Japanese-led team of scientists as they attempt to shed light on the mysterious world of deep sea sharks. Only 50 specimens of the newly discovered 'megamouth' have ever been sighted. Over four years, scientists and film crews voyaged in midget submarines into the depths of Suruga Bay and Sagami Bay to film them. Prehistoric 'living fossil' sharks such as bluntnose sixgill sharks, goblin sharks and frilled sharks also lurk in the bay. As part of the investigation, a sperm whale carcass was placed at the bottom of the bay to attract these sharks, which were then studied and observed from the submersible vessels. Revealing in detail the previously unknown behaviour of deep sea sharks, the film unravels another of the intriguing mysteries of our planet's biodiversity. Narrated by David Attenborough.
The third leg of the adventurer's journey takes him from the south of Kenya to the Horn of Africa. Along the way he joins a Ugandan peace-keeping force in Mogadishu, the capital of war-torn Somalia, which turns out to be the most dangerous leg of his journey as he ends up under fire on the front line. In contrast, he finds neighbouring Somaliland a stable and democratic home to thousands of Somalis fleeing fighting and famine. In Kenya's Tana Delta, he meets villagers facing eviction from an area that the government is turning over to sugar cane production for bio-fuels.

Using the latest technology, David dives into the shark-infested waters of Osprey Reef in the Triton submersible. Sixty years after his first visit to Raine Island, he returns to the nesting grounds of the green sea turtle and at Lady Elliot Island marvels at manta ray cleaning stations. New tracking technology allows David to follow the story of visitors like the dwarf minke whales. Stunning satellite imagery and computer animation reveal their journey and David discovers their surprising reasons for returning and why the reef is vital for their survival.
