大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 45.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9710); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5450)
背棘 (总数) : 11; 背的软条 (总数) : 15; 臀棘: 3; 臀鳍软条: 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).
在第三与第 8根背鳍棘之间的黑色斑点, 鳍也有在身体之上延伸的 2个大的斑块; 身体与背鳍有斑点与斑块边缘蓝灰色.(参考文献 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).
