Luminous beings, creatures with their own internal light, enchant and astonish us. Anyone who has seen a firefly or a glow-worm cannot help but fall under their spell. The sea at night sparkles as millions of luminous plankton reveal the shapes of dolphins in a truly magical light show. But why do animals produce living light? For centuries we could only marvel at the beauty and the mystery, but now for the first time we can begin to reveal the amazing truth about living lights. It has taken three crucial technological breakthroughs. Firstly, colour cameras have improved dramatically; they are now over 4,000 times more sensitive than a decade ago. The cameras are so sensitive they are revealing startling discoveries that until now we could not see. Secondly, scientists have entered the unknown world of the boundless deep open ocean with the help of a new generation of submersibles and robots. Thirdly, Ammonite Films have invented and built a series of unique cameras that can capture the faintest ephemeral glow of luminous life. By combining these three innovations, this film shows creatures and behaviours never seen before. Sir David Attenborough is our guide as we venture into a new hitherto unseen world. Bioluminescence is everywhere: in the soil, on the land and throughout the oceans. Join Sir David Attenborough and a team of the world's leading scientists and deep sea explorers on a quest to reveal the secrets of living lights.
Everyone loves giraffes, but what do we really know about them? Dr Julian Fennessy starts to reveal their secrets - the most important being that they are disappearing. In an urgent and daring mission, with a determined Ugandan team, he plans to round up 20 of the world's rarest giraffe to take across and beyond the mighty Nile River. The stakes are high, but if they succeed the reward will be a brighter future for an animal we have somehow overlooked.

They cannot tolerate sunlight; some of them are even blind. However they are one of the world's most ingenious builders: Termites. They build high-risers that are, relatively speaking, 25 times higher than the Empire State Building in New York. They are the only animals that have managed to build an air-conditioning system without electricity. Their nests are architectural masterpieces that rise up to eight meters from the ground and contain brood chambers for larvae, corridors for transportation and fungal gardens for nutrition. Termites - The Inner Sanctum takes us along a journey into another world. Visit the skillfully built termite mounds in the savannah, termite nests in the tropical rainforest with their colossal columns of termites foraging for food - and the termites that wreak terrible damage to wood-framed homes. Filmed in the US, Kenya and Borneo.

David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 5: Sahara) Northern Africa is home to the greatest desert on Earth, the Sahara. On the fringes, huge zebras battle over dwindling resources and naked mole rats avoid the heat by living a bizarre underground existence. Within the desert, where the sand dunes 'sing', camels seek out water with the help of their herders and tiny swallows navigate across thousands of square miles to find a solitary oasis. This is a story of an apocalypse and how, when nature is overrun, some are forced to flee, some endure, but a few seize the opportunity to establish a new order.

Takes us into the world of digestion and its amazingly complex environment.Our health, body shape, mood and even our evolution are determined by the unseen life forms that swarm throughout our bodies. There are worms in your bowels, bacteria in your mouth, fungi in your lungs and even viruses in your DNA.The combined genetic information of all these bugs is more than 150 times greater than our own genes. Their cells outnumber our own by 10 to 1. This collective menagerie is called the microbiome, and in a very real sense, it is the making of us all.

Zebra stripes vary subtly between the different species but there is one group of animals that has evolved colourful patterns of seemingly infinite variety, the butterflies. In this episode David looks at two examples of animal patterns that have bedazzled and baffled science for a long time, and uses modern tools to unlock their secrets.
