背的软条 (总数) : 3 - 4; 臀鳍软条: 79 - 96. Differs from its sole congener, B. dinema, in having a shorter pectoral fin, 21.9-25.8% SL, versus 25.9-28.9; a shorter head, 20.9-23.9% SL, versus 24.2-26.0; and a shorter snout, 35.4-39.6% HL, versus 39.0-43.1 (Ref. 38432). Strongly compressed head and body; upturned mouth with conspicuous large teeth; pectoral fin longer than head (Ref. 43281).
有别于它的唯一同类, B. dinema, 在有一个方面较短的胸鳍, 21.9-25.8% SL, 对 25.9-28.9; 一个较短的头部, 20.9-23.9% SL, 对 24.2-26.0; 而且一个较短的吻, 35.4-39.6% HL, 对 39.0-43.1.(参考文献 38432) 非常扁长形的头部与身体; 朝上的嘴部具有显着的大齿; 胸鳍长度超过头部.(参考文献 43281)

生物学特性     字汇 (例如 epibenthic)

Occurs in medium to large-sized rivers (Ref. 12975). Found from middle depths to the surface in deeper parts of large rivers. Feeds on smaller fish near the water surface. An excellent game fish which can be caught using hook and line. Presently large numbers are being taken near Stung Treng in Cambodia by explosives (Ref. 12693). Migrates upstream through the Khone Falls in June-July with other silurids and enters the flooded forest in July-October, where it feeds heavily on cyprinids of the genus Henicorhynchus (pa soi, identified as Cirrhinus spp.) (Ref. 38432). Marketed fresh or dried and salted (Ref. 12693).

以其他的鲶鱼溯河回游在六月到七月的经过 Khone 瀑布而且进入在七月-十月被水淹没的森林, 在哪里它吃经常捕食本属 Henicorhynchus 的鲤鱼 (pa soi,鉴定为 Cirrhinus spp了.)。
