Seven dolphins played Flipper, the last of which was named 'Bebe' who was born in 1956 and died May 1, 1997.
Ric O'Barry : Famous "Flipper" Trainer:
Working back in the 1960s for Miami Seaquarium, O'Barry captured and trained dolphins, including the five dolphins who played the role of Flipper in the popular American TV-series of the same name. When Cathy, the dolphin who played Flipper most of the time, died in his arms, O’Barry realized that capturing dolphins and training them to perform silly tricks is simply wrong.
