Sir David Attenborough returns to the Galápagos Islands and travels throughout the archipelago to explain their origins and their unique fauna in evolutionary terms. He has captured a new species of pink iguana on film for the first time. In the first episode, the islands of the Galapagos rose explosively from the ocean four million years ago. Although life would not seem viable in such a remote Pacific outpost, the first arrivals landed as the fires still burned. David Attenborough explores the islands for the animals and plants that descend from these pioneers: from the sea birds carrying the seeds that made a tentative foothold on these rocks, to equator-dwelling penguins and a dancing bird with blue feet. This is a story of treacherous journeys, life-forms that forged unlikely companionships, and surviving against all odds. It is the story of an evolutionary melting pot in which anything and everything is possible.

Jean-Michel Cousteau invites you to embark on a breathtaking underwater voyage to discover the ultimate predator: the shark. Experience an astonishing up-close encounter in 3D with the Lions and Tigers of the Ocean. Come face-to-face with a multitude of shark species, including the Great White, Hammerhead, and Whale Shark. Witness them as they really are: not wicked man-eating creatures, but wild, fascinating and endangered animals that have been in existence a million years before dinosaurs roamed the Earth. Join a team of ocean explorers on a round-the-globe expedition documenting the life of the ultimate predator.

The oceans define the earth. They are crucial to life and we used to think that they were unique to our blue planet. But we were wrong. It has recently been discovered that there are oceans all over our solar system, and they are very similar to our own. And now scientists are going on an epic journey in search of new life in places that never seemed possible. Nasa is even planning to dive to the depths of a strange, distant ocean in a remarkable submarine. Discover that the hunt for oceans in space is marking the dawn of a new era in the search for alien life.

This documentary attempts to make history by finding the lost city of Atlantis once and for all. Adventurer-geologist Dr. Martin Pepper sets out to prove his theory – that the true Atlantis existed on the Greek island of Santorini, and was destroyed in the biggest volcanic eruption in human history". In order to achieve his goal, Pepper will use new scientific evidence gathered using state-of-the-art sonar scans of the sea bed and microscopic analysis of the ancient landscape. One of the challenges he faces is that he must also match Santorini to a series of key clues embedded in the first ever description of Atlantis by the Greek philosopher Plato – from the lost city’s strange ring-shaped design, to the role Egyptian priests played in recording the legend in the first place. His journey will take him across the Mediterranean and out into the Atlantic Ocean. By the end of the program, he reveals the stunning findings which may pinpoint the city and show exactly what it looked like.

In the dark depths of the oceans, nearly 90% of all species light up the darkness from within. These creatures flash, sparkle, shimmer, or simply glow. Whether it’s to scare off predators, fish for prey, or lure a mate, the language of light is everywhere in the ocean depths, and scientists are finally starting to decode it. Discover surprising ways to harness nature’s light—from tracking cancer cells to detecting pollution, lighting up cities, and even illuminating the inner workings of our brains.
