BBC The Natural World. In 2004, a team from the Planet Earth series captured the first ever film of a wild snow leopard in the mountains of Pakistan. For Nisar Malik, who led the expedition, these images sparked a passion that compelled him to return. With cameraman Mark Smith, he spent two years documenting the snow leopard's daily life, finally lifting the veil on the most elusive of all cats.

Squeeze: African Python

The giant squid is a creature of legend and myth which, even in the 21st century, has never been seen alive. But now, an international team of scientists thinks it has finally found its lair, 1,000 metres down, off the coast of Japan. This is the culmination of decades of research. The team deploys underwater robots and state-of-the-art submersible vessels for a world first - to find and film the impossible.

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 depths. As part of the investigation, a sperm whale carcass was placed at the bottom of the sea 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.

The bleakness of Antarctica is a fallacy. The ice continent is full of life and offers a biodiversity of which only about two percent are known. Much of it is under water and could determine the future of human beings. When the northern lights cover the ice landscape in summer, the animals in the Antarctic are in a paradisiacal state. Whales blow their fountains in the sky, penguins fly like small rockets into the water, seals dive for crabs under the glittering ice floes. From the bay of the Ross Sea to the ice shelf, from the huge penguin colonies to steaming volcanoes, a life in rhythm with the ice. But the consequences of climate change are slowly becoming apparent here too. While some species are dying, others are spreading. They could bring new viruses and bacteria with them, and new dangers for humans too. The structure of nature has gotten off course. How many generations will still be able to experience the magic of Antarctica?
