The big blue is the world's greatest wilderness, far from shore and many kilometres deep. It's a vast marine desert where there is little to eat and nowhere to hide. Yet it's home to some of the biggest and most spectacular creatures on earth. This episode reveals what it takes to survive in this savage and forbidding world. We witness feats of incredible endurance, moments of high drama and extraordinary acts of heart-wrenching self-sacrifice. Every animal in the big blue must find their own unique way to survive. Sperm whales have the largest brains in the world. They live for 80 years, and we are only now beginning to learn the extraordinary complexity of their language of clicks - thought to coordinate the whole family in everything from childcare to hunting. With special pressure-proof cameras, we witness record-breaking feats of endurance as they hunt for squid a kilometre down into the abyss. Only recently have we begun to solve the mystery of where baby turtles disappear to in their early years. They leave the crowded waters of the coast and head to the open ocean, where they use floating debris like logs as life rafts. Here they remain until adulthood, adrift on the high seas in relative safety away from coastal predators. Over half of all animals in the open ocean drift in currents. Jellyfish cross entire oceans feeding on whatever happens to tangle with their tentacles. The jelly-like Portuguese man-of-war can harness sail power to fish with its deadly tentacles. Sometimes there is a brief explosion of food in this marine desert, but ocean hunters must be fast to make the best of this bonanza. We witness super pods of up to 5,000 spinner dolphins racing to herd vast shoals of lanternfish, briefly caught at the surface where it is thought they spawn. New aerial footage reveals, for the first time, the truth to a centuries-old sailors' legend of the 'boiling seas' - the spectacular feeding frenzy of 90kg tuna and dolphins smashing through the lantern fish shoals turning the sea white with foam.

The world of bugs normally passes beneath our notice, yet shrink yourself to their size, see them in 3D and you’ll enter a world you’d never believe existed. Big Bugs in 3D uses specially developed 3D technology to take the viewer on a global journey, from Mexico and the rainforests of Asia to our own backyards. There are perhaps four and a half million different kinds of bugs sharing the planet with us. They exist in a bewildering variety of forms, some more like creatures from an alien world. Big Bugs asks how and why these creatures have become so successful.

This immersive series follows the world's most magnificent creatures, capturing never before seen moments from the heartwarming to the outrageous.
In the first episode, majestic, powerful and deadly, big cats were once thought to be solitary creatures. But we're now realizing just how collaborative they can be.

Americans define themselves in the superlative: we are the biggest, strongest, fastest country in the world. They reward above all else: winning – at sport, at business and at war. Metaphorically is a nation on steroids. Is it any wonder that so many of their heroes are on performance enhancing drugs? A film that unflinchingly explores our win-at-all-cost culture. Bigger, Stronger, Faster is a first-person narrative, including US Congressmen, professional athletes, medical experts and everyday gym rats. When you discover that your heroes have all broken the rules, do you follow the rules, or do you follow your heroes?

We can't compare anything on earth to the biggest things known in space. The Cosmic Web may connect objects in the universe with threads of Dark Matter. The Lyman-alpha blob is a bubble like structure containing countless galaxies--perhaps the biggest object in the entire universe. Regions of radio-emitting gas called "radio lobes" could be even bigger. Then there are super galaxy clusters which are hundreds of galaxies merged together due to cosmic collisions. Discover which is the largest planet, star, star cluster, constellation, black hole, volcano, galaxy, explosions, moon, storm, impact crater and "void" in space.

In the past few decades, scientists have learned that the basis of everything they thought they knew about bird brains—that they were largely comprised of the most primitive and instinctual of brain structures—was wrong. Fully 75 percent of the brains of parrots and thousands of other species of birds is actually made up of a sophisticated information processing system that works much the same way as the locus of human higher-mindedness, the cerebral cortex.
The film shows scientists putting birds to the test. Can they solve problems? Can they cooperate? Do they feel emotion? New research demonstrates just how clever they can be.
