Whales and dolphins remain a constant source of fascination. But how much do we really know about them?

Whales and dolphins, known as cetaceans, may appear to be totally alien to us — but with their mental ability, group communication and the recent discovery that dolphins have individual names, they are closer to us than we ever imagined.

This spectacular three-hour film provides new insights into the lives of whales and dolphins in a visually powerful, engaging and entertaining format.

Two of the world’s top underwater cameramen — Doug Allan (“Planet Earth”’s polar specialist) and Didier Noirot (Jacques Cousteau’s front-line cameraman) — film breathtaking encounters. Teams of intrepid scientists equipped with the latest technology are making extraordinary breakthroughs in their understanding of these intelligent life forms — breakthroughs that may safeguard their survival.
