大小 / 重量 / 年齡
成熟度: Lm ? range ? - ? cm
Max length : 34.4 cm TL 雄魚/尚未辨別雌雄; (Ref. 111977)
背棘 (總數) : 0; 臀棘: 0. Scutes apparent along belly. Upper jaw with distinct median notch. Pectoral fin tip short of pelvic fin base by width of 3 to 7 scales; pelvic fin with oblique and almost straight hind margin. Pre-dorsal scales modified; scales on back and above base of anal fin not markedly smaller than rest. A black spot behind gill opening, but none along flank.
Body shape (shape guide): elongated; Cross section: compressed.
鱗甲明顯的沿著腹面。 上頜有明顯的中央凹槽。 3 到 7個鱗片的寬度的腹鰭基底的胸鰭頂端短; 腹鰭有斜角與幾乎直的後緣。 前背部的鱗片修正; 鱗片背面與上方臀鰭基底鰭不顯著地比休息更小。 一個黑色的斑點在後鰓裂, 但是沒有沿著側面。
Forms schools (Ref. 188). The morphological characteristics observed and the composition of the trophic spectrum indicate that this species is a filter-feeder, consuming mainly phytoplankton (Ref. 34154).
