簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 7; 臀鰭軟條: 12 - 13; 脊椎骨: 40 - 41. Distinguished from its congeners, except Batasio batasio, in possessing a color pattern on the body consisting solely of horizontal stripes (vs. with vertical bars and spots, or a uniform dark brown color). Differs from B. batasio in having a shorter dorsal spine (14.0-16.1% SL vs. 16.7-18.5), longer adipose-fin base (28.3-31.8 % SL vs. 24.8-26.5), and a deeper body (19.5-21.2% SL vs. 17.0-17.4) and caudal peduncle (9.3-9.7% SL vs. 8.2-8.8) (Ref. 54041).
除了 巴塔鱨〔Batasio batasio〕 以外，與它的同類區分了, 在獨自地水平斑紋組成的身體上持有一個彩色斑紋方面。 (vs. 具有縱帶與斑點 , 或一個全深褐色的顏色) 在有一個方面有別於 B. batasio 較短的背棘 (14.0-16.1% SL vs.16.7-18.5) ，較長的脂鰭基底 (28.3-31.8% SL vs.24.8-26.5), 與一個較深的身體 (19.5-21.2% SL vs.17.0-17.4) 與尾柄 (9.3-9.7% SL vs.8.2-8.8) 。 (參考文獻 54041)
描述: 臀鰭有 iv,8 或 iv,9個鰭條; 腹鰭有 i,5個鰭條.(參考文獻 54041)
Found in lowland river with turbid water, mainly on sand substrate in lotic areas and sand/mud substrate with some submerged and emergent vegetation in lentic backwaters (Ref. 54041).
用混濁的水發現於低地的河, 主要吃在激流的區域中的沙子底部，而且沙子/泥底部在靜水的洄水區中有一些水下的與突出的植物。 (參考文獻 54041)
