IMAX cameras go underwater for a close-up look at the charismatic marine mammals.
With sunswept ocean locations, the movie is pleasantly diverting both as a science lesson and as a tropical travelogue. Plot Summary Actor Pierce Brosnan narrates this look at wild dolphins and the scientists who study them. These marine mammals have one of the best-developed brains in the animal kingdom. To answer that, the filmmakers turn to researchers like Kathleen Dudzinski, who lives in the Bahamas and studies how dolphins communicate with one another through a peculiar system of vocalized clicks, buzzes, whistles, and silences. Islands away, naturalist Dean Bernal has formed a special bond with one moody, lone dolphin called JoJo, who treats him as a trusted friend, plays with him, and once even defended him against a marauding hammerhead shark.
