| Abstract;The size-advantage model predicts that protogyny is likely to evolve in polygynous species. Polygynous mating systems have been reported from several species of triggerfishes (Balistidae), but sex change has never been confirmed among them. We performed male-removal experiments in the haremic triggerfish Sufflamen chrysopterus on the coral reefs of Sesoko Island, Okinawa. After removal and movement of territorial males, some females became single and later changed body color and sex. This is the first report of sequential hermaphroditism from Tetraodontiformes.
