臀鳍软条: 25 - 30. Dorsum dull grey with pale green iridescence; maxillary band of teeth forms a continuous row with no break in midline (Ref. 12693). Snout protruding with upper jaw tooth bands partly exposed when mouth is closed; large median vomerine tooth plate (Ref. 43281).

背面暗灰色的具有灰绿色彩虹色; 齿的上颌骨条纹形成一个连续的列在中线中没有休息.(参考文献 12693) 当嘴被关闭的时候,吻以部分被暴露的上颌齿箍伸出; 大的中央犁骨齿碟.(参考文献 43281)
Facultative air-breathing (Ref. 126274); Adults occur in large rivers (Ref. 12693) and enters flooded forests (Ref. 9497). They are found in rapids and in deep slow reaches (Ref. 37771). Juveniles feed on prawns and insects; subadults and adults on prawns, insects and particularly mollusks which are more predominant in stomach contents than in any other Pangasius species (Ref. 7432) and on plants (Ref. 9497). They migrate into the middle Mekong along the Thai-Lao border as water levels and turbidity begin to increase. Mature individuals reproduce early in the flood season and juveniles of 6 to 7 cm are taken by late June (Ref. 12693). Marketed fresh (Ref. 12693).
出现于大河 (参考文献 12693) 而且进入被水淹没的森林。 (参考文献 9497) 发现于急流了与在深且和缓的河段中.(参考文献 37771) 稚鱼吃虾与昆虫; 亚成鱼而且成鱼捕食虾, 昆虫与特别地软件动物那是更优越的在胃内含物中超过在任何其他的 Pangasius 种 (参考文献 7432) 方面与在植物上.(参考文献 9497) 游进湄公河中游当水位与浊度开始增加的时候沿着泰寮边界内。 洪水季节初期的时候繁殖,而且 6 到 7 公分的稚鱼被采自六月下旬。 (参考文献 12693) 在市场上销售生鲜地了。 (参考文献 12693)
