The sexual structures of populations of three sparisomatinine parrotfishes from Aldabra (Indian Ocean) are examined and the color phases of each species are described. Notes are given on their ecology and spawning. Leptoscarus vaigiensis evidently is a gonochorist, the first parrotfish known to be so. Calotomus spinidens has both sex-changed males and gonochoristic males, while C. carolinus may have only sex-changed males. In contrast, only sex-changed males have been found in other sparisomatinines examined previously.
