Shamu is name of the Killer Wale very famous at Sea World, San Diego, California. Shamu is the name used for several SeaWorld orca (killer whale) shows and is the stage name given 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 name Shamu was trademarked by SeaWorld (as well as the names “Namu” and “Ramu”) and has been given to different orcas at different times when performing in Shamu shows. It was an amazing show which I have ever witnessed. I visited Sea World, San Diego during my stay in California, during 2008.
