Madagascar is a land just off the coast of Africa that is full of misty mountains, tropical rainforests and spiny desert scrub. It is also home to strange wildlife, much of which is not found elsewhere on Earth. This documentary series, from the BBC's Natural History Unit, showcases the island's diverse and rare wildlife, some of it being filmed for the first time. Among the animals featured on "Madagascar" are lemurs, frogs that change color from brown to yellow, wasps that pluck tadpoles from trees and fish that swim upside down. David Attenborough narrates the three-part series.

Cameras offer incredible views of Galapagos, from erupting volcanoes to stunning vistas and unique wildlife. Viewers can follow Darwin's path as he explored the various islands, observing how nature evolves and adapts to ensure survival. And one episode deals with the most recent threat to these islands -- man.

The most dramatic wildlife spectacles on the planet.

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.
