簡短描述
型態特徵 | 形態測量圖
脊椎骨: 77 - 81. Body firm fusiform, almost cylindrical. Dorsal and ventral surfaces dark; pectoral fin pale distally. Head relatively long (> 21% TL). Mouth moderate, subequal to eye length. Upper eyelid with pale naked patch. Caudal peduncle rather elongate, ca 2-2.6 times greatest horizontal length of D1 including spine about a 5th of TL. Upper teeth of mature males with 7 cusps. Denticles short, robust, arranged in regular rows. Posterior branch of flank marking truncate and merging ventrally with post-pelvic marking. Anterior part of caudal base marking very broad, enveloping ventral surface and extending onto flanks; presence of oval central caudal marking; upper caudal marking comma-shaped. Monospondylous centra 36-38 (Ref. 45056).
