Ric O'Barry was a star dolphin trainer in the 1960s. He created television's first celebrity dolphin, Flipper. But after Flipper died in his arms, Ric made a dramatic U-turn and became an activist, determined that no dolphin should live in captivity. Ric now runs an organisation called Dolphin Project.
