The term SEAWORLD STAR is associated with the iconic Shamu, a killer whale that has been performing at SeaWorld since the 1960s. Shamu is a five-letter word that is often used to refer to any of the killer whales that have performed at SeaWorld over the years. The original Shamu was the first orca ever to be captured and put on display in a public aquarium. Since then, many other orcas have taken on the name Shamu and have become stars of the SeaWorld show.
