Well-developed adipose eye-lid, covering most of eye except pupil in large adults, less extensive in juveniles; presence of a large symphyseal knob in lower jaw fitting in a median notch in upper jaw (Ref. 43281).
發展良好的脂肪眼-眼瞼, 包含的大部分的眼在大的成魚中的除了瞳孔以外, 比較不廣泛在稚魚中; 在上頜中的一個中央的凹槽中的下頜配件中有一個大的合生癤瘤。 (參考文獻 43281)
Inhabits mainstreams of middle reaches in deep rocky rapids. Juveniles occur in tributaries (Ref. 58784). A large fast-swimming predator, feeding on fish of the middle and the upper water levels. Although most common along the Thai-Lao border at the mouth of the Mun River, its numbers have drastically decreased in recent years. This is perhaps due to dam construction or excessive gill netting, to which active pursuit predators, like this species, are particularly vulnerable (Ref. 12693). Undertakes upstream migration at the same time as Probarbus sp. in December-February (Ref. 37770) which may be related to spawning activity (Ref. 9497). Attains over 30 kg (Ref. 9497).
在深的岩石急流中棲息於中游的主流。 稚魚出現在支流。 (參考文獻 58784) 一個大且游速快之掠食者, 吃中上層水域的魚。 雖然最常見的沿著在 Mun 河的嘴巴泰寮邊界, 它的數字有近幾年來大幅減少。 這是也許由於水壩建築或者過多的刺網, 對活躍的追逐掠食者而言, 像這種, 是特別地易受傷害的.(參考文獻 12693) 在十二月-二月 (參考文獻 37770) 那可能是被產卵活動有關的與 Probarbus sp. 同時進行溯溪迴游。 (參考文獻 9497) 達到超過 30 公斤。 (參考文獻 9497)
