SeaWorld is a United States chain of marine mammal parks, oceanariums, and animal theme parks owned by SeaWorld Entertainment.
The parks feature captive 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.
Blackstone sold 19.9 million SeaWorld shares at $27 apiece in the offering.
After accounting for underwriting fees, Blackstone saw proceeds of about $505 million.
After the IPO Blackstone retained a 63% stake in SeaWorld.
In 2003 SeaWorld created the non-profit SeaWorld & Busch Gardens Conservation Fund.
SeaWorld is accredited by the Association of Zoos and Aquariums (AZA), meaning they have met and or exceeded the standards the AZA has set forth in their accreditation standards for Education, Conservation and Research.

An inline twist is a roller coaster inversion in which the rider performs a 360-degree roll.
The inline twist is often found on flying coasters and wing coasters, such as Air at Alton Towers, Batwing at Six Flags America, at Six Flags Over Georgia, Firehawk at Kings Island, Manta at SeaWorld Orlando, Raptor at Gardaland and The Swarm at Thorpe Park.
It can be confused with a heartline roll.
In a heartline roll the center of the train rotates on one axis so the height of the average rider's heart never changes, whereas during an inline twist the train rotates around the track and there is usually little to no elevation difference in the track.
Inline twists are sometimes also known as "barrel rolls". 
A vital part of the Orlando area economy is tourism.
The Orlando area is home to Walt Disney World Resort, Universal Orlando Resort, and SeaWorld Orlando.
Over 48 million visitors came to the Orlando region in 2004.
The convention industry is also critical to the region's economy.
The Orange County Convention Center, expanded in 2004 to over two million square feet (200,000 m²) of exhibition space, is now the second-largest convention complex in terms of space in the United States, trailing only McCormick Place in Chicago.
The city vies with Chicago and Las Vegas for hosting the most convention attendees in the United States.
The Walt Disney World resort is the area's largest attraction with its many facets such as the Magic Kingdom, Epcot, Disney's Hollywood Studios, Disney's Animal Kingdom, Typhoon Lagoon, Blizzard Beach, and Downtown Disney.
SeaWorld Orlando is a large park that features numerous zoological displays and marine animals alongside an amusement park with roller coasters and water park.
Universal Orlando, like Walt Disney World, is a multi-faceted resort comprising Universal Studios Florida, CityWalk, and Islands of Adventure.
The Wet 'n Wild water park is another famous attraction.
SeaWorld Orlando also comprises more than one park, alongside Aquatica and Discovery Cove.
Orlando attractions also appeal to many locals who want to enjoy themselves close to home. 
SeaWorld's main attraction are its orcas, several of which are housed in 7-million-gallon habitats that are each known as Shamu Stadium.
Shamu was the name of the first orca brought to SeaWorld San Diego in the 1960s from the Seattle Marine Aquarium.
'Shamu' is now used as a stage name for orcas in performances at SeaWorld parks.
Currently, SeaWorld houses 23 orcas in its three parks.
Ten orcas live at Seaworld San Diego: Corky, Kasatka, Ulises, Orkid, Nakai, Ikaika, Kalia, Keet, Shouka and Makani.
Seven orcas live at SeaWorld Orlando: Katina, Tilikum, Kayla, Trua, Nalani, Makaio and Malia.
Six orcas live at SeaWorld San Antonio: Kyuquot, Unna, Takara, Sakari, Tuar, and Kamea.
SeaWorld also has five orcas on breeding loan: Keto, Tekoa, Kohana, Skyla and Adan.
Lists of other animals that can be found at each SeaWorld park can be found on each park's individual pages (SeaWorld San Diego, SeaWorld Orlando and SeaWorld San Antonio).
