Maturity: Lm ? range ? - ? cm
Max length : 45.0 cm TL ذكر/ مختلط الجنس; (Ref. 9710); common length : 30.0 cm TL ذكر/ مختلط الجنس; (Ref. 5450)
الأشواك الظهرية (المجموع) : 11; الأشعة الظهرية الناعمة (المجموع) : 15; شوكة شرجية: 3; أشعه شرجية لينه: 15. This species is distinguished by the following characters: short supramaxilla and mostly rigid maxilla with only a slight flexible lamina posteriorly; an ocellated spot on the dorsal fin, between third or fourth and eighth spines followed by two large, irregular, dark blotches that extend onto body, and a blackish streak on cheek bordering upper edge of maxilla; outermost segmented pelvic-fin ray is tightly bound to adjacent ray, with interradial membrane not incised distally or only slightly at tip (vs. interradial membrane deeply incised in all other Indo-Pacific Opistognathus (Ref. 81517).
Black spot between 3rd and 8th dorsal fin spines, fin also with 2 large blotches that extend onto body; body and dorsal fin with spots and blotches bordered with pale blue (Ref. 5468).
This species is occasionally encountered in the fish market and its flesh is reported to be relatively good. It is taken incidentally in bottom trawls and by hook and line at 30-50 m (Ref. 81517).
