大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 45.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9710); common length : 30.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5450)
背棘 (總數): 11; 背的軟條 (總數): 15; 臀棘 3; 臀鰭軟條: 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).
在第三與第 8根背鰭棘之間的黑色斑點, 鰭也有在身體之上延伸的 2個大的斑塊; 身體與背鰭有斑點與斑塊邊緣藍灰色.(參考文獻 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).
