Pete Corselli of La Habra Heights asked scientist Milton Love and Sport Fishing magazine about the identity of this fish, often caught by long rangers fishing on the bottom. It has been called threadfin sculpin, Patina and several other names, but Dr. Love tells us in the August 2013 issue of SF that it is a spotback scorpionfish, Pontinus vaughani, found from Cedros Island to Peru and the Galapagos Islands. Many long rangers regard the fish highly as food. Largest spotback on record was about 22 inches, according to Dr. Love.
