The humpback whale was once hunted almost to extinction, and now that it is under the protection of conservation laws, it has experienced a rebound in numbers. Found in climate extremes from the coasts of Alaska and Antarctica to the warm waters around the Pacific islands of Fiji and Tonga, this remarkable creature is studied in Nature: Humpback Whales. Underwater footage reveals the competitive males as they fight for mates, and the special relationship of calves to their mothers. Secrets of their hunting strategies are revealed, as they are filmed herding fish with nets made of air bubbles.
