When and where did Marineland, the first large oceanarium, open?

The world’s first large oceanarium, known as Marineland of Florida, opened to the public in 1938. It is located approximately 20 miles (32 km) south of St. Augustine, Florida, in the United States.123

Originally named Marine Studios, the facility was designed as an underwater studio for filming marine life and featured large community tanks that allowed for the display of a wide variety of species together. Beyond its role as a tourist attraction, the site became a significant center for scientific research, including the development of procedures for maintaining marine life in artificial environments and the study of dolphin behavior.123
