We think of the lion as the king of beasts - the perfect predators - built to make a swift clean kill - but think again. Now spectacular footage reveals another side to this hunters killing power. We follow a family of lion cubs as they start out in life. Seven out of the eight cubs are male - for them the clock is ticking, within two years they need to learn to hunt before setting out and finding new territories of their own, to avoid treading on the toes of the dominant pride male. The cubs hunting lessons are perhaps not what you might expect; instead of ambushing their prey and quickly despatching with a clean bite to the throat, these lions wrestle their victim to the ground and tuck in before the hapless beast is dead. When the prey is a young elephant, it means a slow and painful death. Are these lions behaving badly or is it simply that this is what lions do?

The waters of the North Pacific around Canada's Vancouver Island are a strange and little known world. The water is incredibly clean, the location is isolated and huge thermal vents heat the otherwise cold surrounding these factors combined have led to animals and plants that can grow to huge proportions. Humpback whales, orcas, wolf eels and bald eagles all thrive here. Our team of experts go in search of the elusive Pacific Giant Octopus. Growing up to 7.5 meters across with the power to kill sharks, it is a formidable creature, but also intelligent and incredibly shy. The dive team invites us into an alien world, where persistence is rewarded with encounters with three of these magnificent creatures.

This is his story. How does it feel to live amidst a group of the most feared predators on the African continent as they fight to survive in a harsh, unforgiving world? Jurgen's film shows what it's like and is the result of his remarkable adventures. Jurgen is one of the world's premier wildlife photographers. His story of his life with these lions is one that spans a period of political struggles, disease and drought, showing the highs and the lows of life in the lion pride.

We take an exclusive peek into the mysterious lives of the most secretive animals of the African Bushveld. For the first time ever, we take an exclusive peek into the mysterious lives of the most secretive animals of the African Bushveld. We will expose the behaviors of these animals seldom, if ever, seen before as we delve into the shadowy existence of animals rarely seen, let alone captured on television. We will investigate seven enigmatic creatures - the serval, aardvark, pangolin, genet, African wildcat, civet and porcupine - as they furtively go about their top-secret activities. Each story will introduce us to one of these animals, and give us a privileged glimpse into their extremely private lives and their particular adaptations for life in the dangerous wilderness, where they battle against tremendous odds. We witness how each one cunningly outwits the super-predators in its own special way, with extra-sharp senses and other strategies for survival.
