SeaWorld is a United States chain of marine mammal parks, oceanariums, and animal theme parks owned by SeaWorld Entertainment. The parks feature orca, sea lion, and dolphin shows and zoological displays featuring various other marine animals. There are operations in Orlando, Florida; San Diego, California; San Antonio, Texas; and previously Aurora, Ohio. On March 5, 2007, SeaWorld Orlando announced addition of the Aquatica water park to its adventure park family, which already includes SeaWorld and Discovery Cove. SeaWorld parks also feature a variety of thrill rides, including roller coasters like Kraken and Manta at SeaWorld Orlando and Steel Eel and The Great White at SeaWorld San Antonio. Journey to Atlantis, a combination roller coaster and splashdown ride, can be found at all three US parks. The parks were owned by Busch Entertainment Corp., the family entertainment division of Anheuser-Busch, which is best known for brewing beer. In November 2009, Busch Entertainment was sold to the Blackstone Group and subsequently renamed SeaWorld Entertainment. On April 19, 2013 SeaWorld Parks & Entertainment had an initial public offering of stock.
