SeaWorld's main attraction is its killer whales, several of which are housed in 5.8-million-gallon tanks (equivalent to nine Olympic sized swimming pools)[25] that are each known as Shamu Stadium. Shamu was the name of the first killer whale brought to SeaWorld San Diego in the 1960s from the Seattle Marine Aquarium. 'Shamu' is now used as a stage name for killer whales in performances at SeaWorld parks. Currently, SeaWorld houses 22 killer whales in its three parks.
Ten killer whales live at SeaWorld San Diego: Corky, Ulises, Orkid, Nakai, Ikaika, Kalia, Keet, Shouka, Makani and Amaya.
Six killer whales live at SeaWorld Orlando: Katina, Kayla, Trua, Nalani, Makaio and Malia.
Five killer whales live at SeaWorld San Antonio: Kyuquot, Takara, Sakari,[26] Tuar and Kamea.
