The great whales – such as the blue and the bowhead – are the largest animals that have ever lived on our planet. Yet these mighty leviathans feed on tiny shrimp and sardines. “Giant Lives” discovers why size matters in the world of whales.

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 series provides new insights into the lives of whales and dolphins in a visually powerful, engaging and entertaining format.
