David Attenborough investigates the mysterious and unique wildlife of the dry southern lands of Madagascar.

The eastern portion of the island is home to ring-tailed lemurs, jeweled geckos and predatory wasps.

David Attenborough tells the story of one of the most intriguing wild places on Earth, Madagascar; in splendid isolation, Madagascar has evolved its very own quite extraordinary wildlife, more than 80 per cent of it is found nowhere else.

Whenever documentary filmmakers at Discovery Channel and the BBC unite for a project, stellar television seems to follow. "Planet Earth: Africa" stems from this collaboration, as did the breakthrough natural history series "Life" in 2009. David Attenborough narrated that one, and he's back to take viewers on a journey through the vast and diverse continent of Africa. Four years in the making, during which more than 2,000 hours of video were shot, the program consists of six hour-long episodes that feature an array of never-before-filmed species, animal behaviors and previously unknown places. Cameras uncover the extreme dangers of the Kalahari, the dense forests and snow-capped peaks of the Savannah, the dynamic Congo rainforest, the ever-changing climate of the Cape and the massive and parched Sahara.

The planet is teeming with myriad life forms, both plant and animal, all interlocked in a struggle for survival. As time goes on, some living things are forced to adapt and change to survive. This series chronicles some of the most unusual, if not downright bizarre, behaviors that living organisms have devised to keep their species alive. The 11-episode series was four years in the making, taking camera crews to every continent and habitat.

Produced by the team that created BBC's "Planet Earth" series, "The Hunt" explores the relationship between predators and their prey. Sir David Attenborough narrates this documentary while the cameras follow the animals in their natural habitats. With a specific focus on strategy, the hunters are examined in detail -- from their use of the environment to their sharp instincts and physical prowess. On the other side of the fence are the hunted, which use their senses and defense tactics to flee when they feel threatened. Each episode centers on a different habitat, and the last one focuses on the state of the planet.

"Dynasties" is a documentary by Sir David Attenborough as he goes on a journey behind some of the most celebrated and endangered animals on the planet. Follow the stories of penguins, chimpanzees, lions, painted wolves, and tigers. Each of these animals is locked in a heroic struggle against the forces of nature and their rivals -- they face harsh environmental conditions, dangerous predators, and even the greatest threat: humans. They actively seek to fight for their survival and the survival of their families -- their dynasties.
