Coelacanth (SEEL-uh-kanth): a large fish with limblike fins, armored scales and a tail that no other living fish possesses. This prehistoric fish was thought to have died out with the dinosaurs in the great extinction. It has laid hidden deep in our oceans undisturbed and undetected for 70 million years—a true living fossil. The coelacanth is thought to be related to the creatures that grew legs, breathed air and came ashore nearly 400 million years ago.

The southern coast of Africa features an array of battlefields as diverse as the predators who reign over them. In this concentrated mix of environments, lions rule the grasslands and leopards dominate the thick brush. Nile crocodiles and sharks rule the waters, while gannets control the skies. But all must bow to the power of the coastal plain's seasons: a ruthless cycle that has the power to give life and take it away. Enter these diverse domains and see how all creatures, hunters and hunted, must have a plan to survive the Predator Coast.

In this traditional blue-chip documentary we show a dramatic comparison between two environments fed by the same stock of sardine, and dominated by the Cape gannets.

The Amazon is one of the wildest and least explored parts of the planet. Encompassing 6 countries and 2 million square miles of forest, river and floodplain, it has the highest diversity of life on the planet, but what lies below it is truly shocking. In its deep muddy rivers, clear streams and expansive floodplains a freak-show of fish life has exploded, with some of the strangest shapes and weirdest adaptations on Earth. Hiding in the vast rivers and streams is an electric grid, a bizarre community of fish with a highly sophisticated electric sixth sense. Using electricity, these "Super" fish can communicate wirelessly, control each other remotely and emit shocks that can stop a human heart. This cryptic world has mystified scientists throughout the ages. Now an intrepid scientist, Will Crampton ventures back into the dark jungles where the inspiration for our technology driven world first emerged, in an attempt to unravel their secrets and unlock the electric code.

A routine drone survey turns deadly when Ryan Johnson, a marine biologist based in South Africa, films a humpback whale being attacked and strategically drowned by a Great white shark. This is a total perspective shift for the creature.

This series studies an array of predatory models in each location, and then looks at why particular animals are able to lift themselves above the rest. Sometimes starvation drives predators to the extreme – as in Savute, where a particular lion pride unlocks the key to hunting elephants. Or vicious competition drives them to hyper-efficiency – as in Ndutu, where cheetahs team up to out-hunt hyena mega-clans… Or sometimes the chance to kill comes so rarely that when it does appear every effort is put into the killing blow – as at the Grumeti river, where massive crocodiles wait an entire year for one feast This is the NatGeo version of "Africa's Predator Zones"

On the harsh and unforgiving plains of central Namibia, Africa, a young honey badger named Grit has just left home to venture out in the great, wide world, but it won't be easy. Fewer than half of all young honey badgers survive their first few weeks on their own, as they deal with intense heat, starvation, and round-the-clock threats from the many predators of the savannah.

This film uncovers a hidden world ruled by hairy eight-legged monsters known as the Arachnids - the largest group of carnivorous creatures on earth. High speed cameras and detailed macro photography reveal a variety of deadly hunting tactics used by this sinister network of freaks.

When the night falls, the sky comes alive. A flutter of wings that, for some, is the stuff of nightmares. One in every four mammals on the planet is a bat. But fear for these creatures is often misplaced, not all bats are blood-sucking beasts. The world of bats is incredibly diverse with some beautifully bizarre adaptations.

South African extreme fisherman Andy Coetzee embarks on an epic series of adventures to reel in some of the world's most elusive and iconic fish species.

Documentary which follows crocodile expert Brad Bestelink on a quest to dive with crocodiles without a cage or any other protection.

For thousands of animals every year, migrating across Patagonia is the only chance of survival as they return to give birth and raise their young or come home to feed.

A caving expedition recently discovered a community of dwarf crocodiles living in the Abanda Caves, Gabon. The crocs are living in pitch darkness, hunt bats and some have bright-orange skin. Part of the original team returns to find out more about this bizarre phenomenon. It's mission impossible to access the crocs world and there's no way of knowing what they might find.

The ragged-tooth shark has a formidable reputation – but the truth about this animal is very different. We follow this incredible shark on its biannual migration along the South African coast and venture deep into underwater caves to study its dramatic mating behaviour.

Enter the battlefields of Africa, arenas bathed in a history of savagery and blood, where big cats and big crocs have reigned supreme for centuries. Here in the open plains, muddy swamps, and deep rivers, these super predators don't simply survive in hostile and unforgiving conditions, they thrive because of them. See how these four-legged assassins adapt to their surroundings and use the terrain to unlock new hunting techniques, seek out new prey, and amplify their age-old skills by using the lay of the land.

There is an island where dragons still roam. A Jurassic type underworld where ancient warlords still rule. Where they fight for supremacy...where they fight to survive. Komodo Island - deep in the remote basin of the Pacific Ocean - its an ancient Kingdom of fire and brimstone. Here, a string of 452 volcanoes erupt from the ocean bed, its known as "The Ring of Fire" and it's the perfect habitat for dragons. Komodo Dragons! The largest living lizard on the planet with 34 million years of survival in his DNA. Its no surprise that he's still known as a dragon, he has the presence of an ancient gladiator. He's armored in claws and scales, but instead of spitting fire, he spits deadly venom.
