Far from civilization, a team of scientists, led by Dr. Enric Sala and joined by Explorer-in-Residence Mike Fay, search in a wilderness of waves for ancient secrets and living treasures. In the most comprehensive survey ever attempted, our scientists discover a hidden world found no where else on earth. Full of coral, fish, and, especially, sharks - this is a world where predators outnumber prey. What they find could change our understanding of coral reefs forever. Enric Sala and his team search for the key to save our planet's reefs... in a hidden paradise called Shark Eden.

An epic story of Australian and international scientists who are racing to understand our greatest natural wonder and employing cutting edge science in an attempt to save it.

Even the biggest, fastest and fiercest predators start as babies. Baby sharks are cute, but they need to grow up fast because out of more than 500 species of sharks, not one parent sticks around to help raise them. Sharks are found in every ocean across the planet and have evolved in extraordinarily different ways to carry their young and give birth and for baby sharks to thrive.

Almost 70 years after its sinking, the powerful headlights of two high-tech research submersibles illuminate the silhouette of the biggest German battleship ever. The pride of the German Kriegsmarine: Bismarck. In 1941 the Bismarck was sent out to raid and destroy allied supply convoys in the North Atlantic. With resources vital to their nation under threat, the British fleet went after this supposedly unsinkable ship. But who actually sank the steel giant?

In recent years, an unusual spate of deadly shark attacks has gripped Australia, resulting in five deaths in 10 months. At the same time, great white sharks have begun appearing in growing numbers off the beaches of Cape Cod, Massachusetts, not far from the waters where Steven Spielberg filmed Jaws. What's behind the mysterious arrival of this apex predator in an area where it's rarely been seen for hundreds of years? Are deadly encounters with tourists inevitable? To separate fact from fear, NOVA teams with leading shark experts in Australia and the United States to uncover the science behind the great white's hunting instincts. With shark populations plummeting, scientists race to unlock the secrets of these powerful creatures of the deep in their quest to save people -- and sharks.
