About National Shamu the Whale Day
Shamu was a killer whale (orca) that appeared in shows at SeaWorld San Diego in the mid/late 1960s. She was the fourth orca ever captured, and the second female. She was caught in October 1965 and died in August 1971, after about six years of performance. After her death, the name Shamu continued to be used in SeaWorld "Shamu" shows for different orcas in different SeaWorld parks.
Shamu was originally captured to be a companion for a male killer whale Namu. (She-Namu)
