The Miami Seaquarium is a city park on the island of Virginia Key in the Bay of Biscayne, which houses a dolphinarium where performances of trained animals are also held. The park has about 225 employees and is the third largest contributor to Miami-Dade County. Founded in 1955 by Fred D. Coppock and Captain WB Gray, it is the oldest marine aquarium in the United States of America and the second attraction on marine life in South Florida. At the time of its inauguration it was also the most great in the world. From 1963 to 1967, at the Miami Seaquarium were recorded 88 episodes of the television series Flipper and two films on the same subject. In 1983, in the scenes of the fistfight and the waterfowl of the orca of the film Nati with a shirt, the Seaquarium was chosen. The park offers daytime shows and overnight stays, boy scout events, and group programs. The structure is visited by over 500,000 people a year. The park is equipped both with tanks for marine animals, both with areas for land animals. The aquatic exhibition tanks are the Golden Dome Sea Lion Show (for sea lions), the Top Deck Dolphin Show and the Flipper Show (for dolphins) and the Killer Whale Show (for killer whales). One of the main attractions of the Miami Seaquarium, in fact, is Lolita, the only orca orca present in the park. Lolita arrived at the Miami Seaquarium in 1970, where she reached the first orca hosted in the Seaquarium, Hugo. At the base of the Dolphin Show Top Deck there are aquariums for tropical fish, while the Manatee Exhibit is an additional tank that hosts an exhibition of manatees. Shark can be observed in the Shark Channel, while birds and reptiles are found in Tropical Wings and Crocodile Flats.
