Humpback whales have one of the most complex songs of all animals. Scientists do not yet know exactly what they mean, but males sing vigorously during the breeding season on Silver Bank, in the Dominican Republic. Scientists from the oceanographic schooner Sedna IV slip into the crystal clear water with them to try and unravel the mystery of one of the most spectacular sonic phenomena in the animal kingdom. During these dives, calves play with the divers, a touching demonstration of mutual curiosity. Some Alaskan humpbacks also use songs to synchronize hunting among schools of herring. Practiced by a small number of humpbacks who prefer to hunt in groups, this technique combines a strident call with the formation of a bubble-net, which traps the fish.
