David Attenborough takes a breathtaking journey through the vast and diverse continent of Africa as it has never been seen before. (Part 4: Cape) Southern Africa is a riot of life and colour because of two great ocean currents that sweep around the continent's Cape. To the east, the warm Agulhas current generates clouds that roll inland to the wettest place in southern Africa. To the west is the cold Benguela current, home to more great white sharks than anywhere else. Moisture laden fog rolls inland, supporting an incredible desert garden. Where the two currents meet, the clash of warm and cold water creates one of the world's most fabulous natural spectacles - South Africa's sardine run. This is the greatest gathering of predators on the planet, including Africa's largest, the Bryde's whale.

Hummingbirds represent one of nature's most interesting paradoxes - they are the tiniest of birds, yet they qualify as some of the toughest and most energetic creatures on the planet. New knowledge gained from scientists currently making great breakthroughs in hummingbird biology makes this a perfect time to focus on these shimmering, flashing jewels of the natural world. Stunningly beautiful high-definition, high-speed footage of hummingbirds in the wild combined with high-tech presentations of their remarkable abilities help us to understand the world of hummingbirds as we never have before.

"Strange Parents" asks how we usually recognise animals as either male or female and how each sex normally plays a particular role in their own life cycle. However both hyenas and seahorses completely break the gender rules.

Groundbreaking documentary which follows a Japanese-led team of scientists as they attempt to shed light on the mysterious world of deep sea sharks. Only 50 specimens of the newly discovered 'megamouth' have ever been sighted. Over four years, scientists and film crews voyaged in midget submarines into the depths of Suruga Bay and Sagami Bay to film them. Prehistoric 'living fossil' sharks such as bluntnose sixgill sharks, goblin sharks and frilled sharks also lurk in the bay. As part of the investigation, a sperm whale carcass was placed at the bottom of the bay to attract these sharks, which were then studied and observed from the submersible vessels. Revealing in detail the previously unknown behaviour of deep sea sharks, the film unravels another of the intriguing mysteries of our planet's biodiversity. Narrated by David Attenborough.

David uses the latest 3D technology to explore a world beyond the confines of our human senses. He begins with the secret world of plant movement and uses sinister carnivorous plants to show just how active plants can be. Bladderwort utricularia is a pond-dweller that is among the fastest known, its traps snapping shut in less than a millisecond. As the seasons change, David demonstrates how plants operate on a different time scale to us; how they modify their lives according to the time of year. We discover insects' hidden links with plants, both as pests and ...
