Dolphin Days (Full Show) at SeaWorld San Diego on 8/30/15

SeaWorld San Diego is an animal theme park, oceanarium, outside aquarium, and marine mammal park, in San Diego, California, United States, inside Mission Bay Park. The park is owned by the City of San Diego and operated by SeaWorld Entertainment.

SeaWorld San Diego is a member of the Association of Zoos and Aquariums (AZA).[3] Adjacent to the property is the Hubbs-SeaWorld Research Institute, which conducts research on marine biology and provides education and outreach on marine issues to the general public, including information in park exhibits


SeaWorld was founded on March 21, 1964 by four graduates of the University of California, Los Angeles. Although their original idea of an underwater restaurant was not feasible at the time, the idea was expanded into a 22-acre (8.9 ha) marine zoological park along the shore of Mission Bay in San Diego. After an investment of about $1.5 million, the park opened with 45 employees, several dolphins, sea lions, and two seawater aquariums, and hosted more than 400,000 visitors in its first year of operation.[5]

Initially held as a private partnership, SeaWorld offered its stock publicly in 1968 enabling them to expand and open additional parks. The second SeaWorld location, SeaWorld Ohio, opened in 1970, followed by SeaWorld Orlando in 1973 and SeaWorld San Antonio (the largest of the parks) in 1988. SeaWorld Ohio was later sold to Six Flags in January 2001.[5] The parks were owned and operated by Harcourt Brace Jovanovich between 1976 and 1989, when they were purchased by Anheuser-Busch Companies, Inc. After Anheuser-Busch was acquired by InBev, SeaWorld San Diego and the rest of the company's theme parks were sold to the Blackstone Group in December 2009, which operates the park through its SeaWorld Parks & Entertainment division.[2]

SeaWorld currently leases the land from the City of San Diego with the lease expiring in 2048. The premises must be used as a marine mammal park, and no other marine mammal park may be operated by SeaWorld within 560 miles of the City limits
