簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 1; 背的軟條 (總數) : 6; 臀鰭軟條: 6; 脊椎骨: 31 - 34. Differs from other members of the genus in possessing a narrower nuchal plate (width equal to length vs. width 1.2-1.3 times length); larger eye (13.2-16.3% HL vs. 6.9-12.2) and a longer snout (56.2-60.3% HL vs. 53.9-55.9) , except for Sisor torosus. Can be distinguished further from Sisor rabdophorus and Sisor chennuah in having a narrower head (14.5-14.8% SL vs. 15.1-17.7) (Ref. 55921).
在持有一個比較狹窄的頸背碟方面有別於其他本屬的成員;(寬度倍長度等於長度和寬度 1.2-1.3 比較) 較大的眼 (13.2-16.3% HL vs.6.9-12.2) 與一個較長的吻 (56.2-60.3% HL vs.53.9-55.9), 除了 Sisor torosus 。 能從 Sisor rabdophorus 與 Sisor chennuah 在有一個方面被區別進一步較狹窄的頭部 (14.5-14.8% SL vs.15.1-17.7) 。 (參考文獻 55921)
Inhabits swift-flowing rivers with sandy bottoms (Ref. 55921).
