March 26, 1980: Head dolphin trainer Patricia Fiorelli, got two of her dolphins to stand on their tails during the popular dolphin show held in the ship, Discovery, that was moored next to the aquarium. In 1991, the aquarium dropped its dolphin exhibit. At that time, they had one 12-year-old female dolphin who needed company other than the two adolescent male dolphins in the tank and the facilities were too small to add more of these animals. So the female was sent to the Brookfield Zoo in Chicago and the males were sent to the Dolphin Research Center at Marathon Key, Fla.
