to reduce possible public confusion. The origin of the name "dolphinfish" is recent, to avoid confusion with dolphins, as the traditional name of the fish was also "dolphin". Why the mammal and the fish were both called "dolphin" is uncertain, but theories include that dolphinfish communicate using high-pitched sounds similar to a dolphin, and they are about the size of a small dolphin, or due to ''dorado'' (Spanish for "golden") having been purportedly used historically in Spanish for both dolphins (normally ''delfín'') and dolphinfish.
