Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 3; Dorsal soft rays (total): 24 - 25; Anal spines: 3; Anal soft rays: 12 - 13. This species distinguished by the following characters: 24-25 (usually 24) segmented dorsal-fin rays; 12-13 (usually 13) segmented anal fin rays; 18-25 anterior lateral line scales; 16-20 (usually 20) circumpeduncular scales; relatively stout and pungent anal-fin spines, the second much stouter than the third; color in alcohol consisting of pale central spots on scales of flanks behind pectoral fin base and dark central spots on breast scales (Ref. 81967).
Body shape (shape guide): elongated; Cross section: compressed.
Known from coral reefs in harbours and near mangrove areas (Ref. 81967).
