Shamu is the stage name given to the SeaWorld orca (killer whale) shows and to the "star" of those shows, beginning with the original Shamu in the late 1960s and early 1970s. The orca Shamu died in 1971, but the names Shamu (and "Namu" and "Ramu") were trademarked by SeaWorld and have been given to different orcas at different times when performing in Shamu shows.
