背棘 (总数) : 1; 背的软条 (总数) : 7; 臀鳍软条: 12 - 14; 脊椎骨: 44 - 46. Can be differentiated from its congeners by a unique combination of the following characters: head length 31.0-34.3% SL; dorsal to adipose distance 7.3-10.9% SL; length of dorsal-fin 27.3-30.8% SL; post-adipose distance 14.7-16.2% SL; interorbital distance 28.1-31.1% HL; presence of filamentous extensions on the first three dorsal-fin rays in adults (Ref. 38441). Depressed dorsal fin reaching adipose fin; adipose fin same color as body; body and fins a uniform dark brown; crenulate ridge along anterior edge of pectoral spine; 8 branched anal-fin rays (Ref. 12693). Elongated upper caudal lobe ending in a filament (Ref. 43281).
能被与它的同类区别藉着下列特徵的一个独特组合: 头长 31.0-34.3% SL; 背鳍到脂鳍距离 7.3-10.9% SL; 背鳍长 27.3-30.8% SL; 后脂肪的距离 14.7-16.2% SL; 眼间距 28.1-31.1% HL; 在第一个上有丝状的延长三个背鳍鳍条当成鱼时。 (参考文献 38441) 扁平的背鳍达到脂鳍; 脂鳍相同的颜色当身体; 身体与鳍全深褐色; 细齿状的脊沿着胸棘的前缘; 8个分枝的臀鳍棘条.(参考文献 12693) 延长的末端形成一个丝状突起的上尾部的叶。 (参考文献 43281)
Inhabits slowly flowing or standing waters of the lower Mekong. Moves into flooded forests during periods of high water levels. Feeds on crustaceans and fishes. Marketed fresh (Ref. 12693).
栖息于下面湄公河的流速缓慢或不流动水域。 在高水位水平的时候移入被水淹没的森林。 吃甲壳动物和鱼类。 在市场上销售生鲜地了。 (参考文献 12693)
