成熟度: Lm ? range ? - ? cm
Max length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. ); common length : 40.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 6077)
背棘 (總數) : 5 - 6; 背的軟條 (總數) : 33; 臀棘: 3; 臀鰭軟條: 33 - 41; 脊椎骨: 27. First dorsal fin composed of several short spines preceded by an anteriorly directed spine usually completely embedded under skin. Two detached anal spines anterior to soft anal fin. Lateral line curved and undulated, with more or less 10 branches anteriorly and fairly straight posteriorly (Ref. 27363). A black patch on the opercle is a conspicuous character of this species, thus the name signata (Ref. 3157).
Body shape (shape guide): fusiform / normal.
第一背鰭在皮膚下面前面有一根朝向前面的棘一些矮棘通常完全地組成埋入。 二個分離的臀鰭硬棘位於軟的臀鰭前。 側線彎曲了而且波動了, 藉由約略 10個分支前面地與相當筆直地在後部.(參考文獻 27363) 在鰓蓋上的一個黑色斑點是一個這種的顯著特徵, 如此名稱 signata.(參考文獻 3157)
Maximum length assumed to be 1.5 * 40 = 60 cm TL (RF).
最大的長度可能是 1.5*40=60 公分TL(RF) 。
