Shamu was the first orca to survive more than 13 months in captivity and was the star of a very popular killer whale show at SeaWorld San Diego in the mid - late 1960s. She was the fourth killer whale (orca) ever captured (the second female) and was the third orca ever displayed in a public exhibit. After her death in 1971, the name Shamu continued to be used in SeaWorld "Shamu" orca shows for different killer whales in different SeaWorld parks.
Shamu represents the first successful intentional live-capture of a healthy orca. Three previous orca captures (including Moby Doll and Namu) had been more opportunistic. The way Shamu got her name was from Namu, She+Namu=Shamu. The very young (14 foot / 4.25m, 2000 lb / 900 kg) Southern Resident orca was captured by Ted Griffin in Puget Sound in October 1965 to be a companion for the orca Namu at Griffin's Seattle public aquarium. But the new orca was soon leased to and then purchased by SeaWorld in San Diego in December 1965. She was retired from performing after an incident in which she grabbed and refused to release the leg of a female SeaWorld employee who was riding her as part of a filmed publicity event.
