More Info

Distribution	Hibernia Reef, Western Australia, to Cartier Reef, Timor Sea, the northern Great Barrier Reef to at least One Tree Island, Queensland, and reefs in the Coral Sea; also Cocos (Keeling) Islands and Christmas Island in the eastern Indian Ocean. Elsewhere the species is widespread in east-Indo-west Pacific.
Features	Dorsal fin VI + I, 9; Anal fin 8-9: Pectoral fin 17-18; Longitudinal scale series 26-27; Transverse scales 7-8. Body depth 3.9-4.2 in TL; first dorsal fin with second spine longest; rays of 2nd dorsal nearly equal; anal fin similar to 2nd dorsal; pectoral fin reaches to vertical of anus; pelvic fins lacking frenum but connected to basal membrane; Body with ctenoid scales except ventral midline and pectoral base with cycloid scales; predorsal scales absent; cheek and opercle without scales.
Similar Species	The very similar Trimma okinawae has no large red spots on the pectoral-fin base and lacks predorsal scales.
Etymology	The specific name macropthalmus isfrom the Greek makros (large) and ophthalmos (eye), presumably in reference to the large eye of this species.
