The individual was donated to the Scripps Institution of Oceanography Marine Vertebrates Collection (SIO 07-71), which held the four previously reported California collections. This specimen represents the first collection north of San Diego Bay, California. It is presumed this individual was present in the Huntington Beach, California area due to higher than normal seawater temperatures recorded during the ENSO event of 1982 (Lea and Rosenblatt 2000). This individual is substantially smaller than all of the previously known specimens. All previous collections were provided by fishermen, both commercial and recreational.
