Populations in the Pacific Ocean are found in the Gulf of Thailand, Malaysia, Indonesia, the Philippines, Taiwan, Japan, the Yellow Sea, the Great Barrier Reef around Australia, New Zealand, and Pacific islands all the way to Hawaii. They were also recently thought to have been found in the Mediterranean Sea but it has been found that the majority, if not all, of the specimens from the Mediterraean are of Abudefduf saxatilis, an Atlantic species.
