簡短描述 型態特徵 | 形態測量圖

背的軟條 (總數): 117-128; 臀鰭軟條: 97 - 108; 脊椎骨: 66 - 70. This fine-scaled species have the following characteristics: pyloric caeca usually 5-6, typically 5 + 1; usually 3 rudimentary gill rakers on the upper arm of the first arch and 4-5 developed rakers on lower arm with 2-5 rudimentary rakers anteriorly, total gill rakers usually 11-12 (10-15); count of scale rows almost 30 between the occipital line and the dorsal-fin origin, 14-15 rows between the dorsal-fin origin and the lateral line, and about 255 lateral scale rows; dorsal-fin origin between neural spines 4-5 (rarely between 3-4); color of head and body rather uniformly dusky, silvery, or whitish along the belly; dorsal fin usually lacks a dark edge, and when present it is poorly developed; anal fin has an inconspicuous and narrow dark edge; orobranchial cavity usually pale, but the rear of the roof of the mouth may be dusky; esophagus blackish; stomach and hindgut pale (Ref. 91765).
嘴的棘長的而且彎曲了, 達到吻尖, 沒有垂直的基部組成; 腹膜灰白的; 沒有中央的基鰓骨齒列; 頭部廣泛地覆蓋著重疊成瓦狀的列了圓形的鱗片除了吻與咽喉; 身體逐漸變細成為尖點, 匕首形的.(參考文獻 34024) 身體相當均勻著色, 些微腹面灰白或只有一系列的深色破折線沿著側線,否則斑紋侷限於垂直的鰭了; 食道黑色,鰓室與口腔灰白的; 背鰭無斑點的.(參考文獻 34024)
