More Info


Houtman Abrolhos to Cassini Island, Western Australia, and the far northern Great Barrier Reef, Queensland, to the Solitary Islands, New South Wales; also the Lord Howe Province in the Tasman Sea. Elsewhere, the species occurs in the tropical, Indo-west Pacific. Inhabits sandy and coral rubble areas in coastal waters, often at the base of coral overhangs.


Dorsal fin VI + I, 9; anal fin I, 7-8; Pectoral fin 17-20; Longitudinal scale series 25-26.
Body depth 4.8-5.2 in SL. First two dorsal-fin spines filamentous, especially in males; pelvic fins fully united; pelvic frenum present; gill opening extending to below posterior half of operculum.
Scales mostly ctenoid except cycloid on nape, breast and pectoral-fin base; scales on side of nape extending to level of eyes; median predorsal scales absent.


Forms spawning pairs that nuture the egg clusters.


The specific name inframaculatus is from the Latin infra- (= inner) and maculatus (= spotted) in reference to the elongate internal black-and-white spots (or dashes).
