Body width 14.9-17% SL; predorsal length 34.6-36.1% SL. Large vomerine tooth plate bordered by long and slender palatine tooth plates. A 2-chambered swim bladder is confined to the abdomen.
身體寬度 14.9-17% SL; 前背的長度 34.6-36.1% SL。 大的犛骨齒碟與長且細的上顎齒板接壤了。 一 2-腔室的泳鰾侷限於腹部了。
Facultative air-breathing (Ref. 126274); Collected from freshwater near the mouth; inhabits large pools near the sea, with deep and turbid waters. In the upper reaches, inhabits torrential areas with clear water (altitude 200-400 m). Immature specimens occur all over the basin; mature ones apparently present only in the upper reaches in running water. Mature ones observed to be able to cross major waterfalls by jumping out of the water. Reproductive behaviors unknown. Predominant in the stomachs of small specimens were mollusks; large specimens with skeletal remains of small cyprinid species and fruits (Ref. 40416).
採集自淡水的河口附近了; 居住於在海洋附近的大的水池,藉由深的而且混濁的水域。 在上游中, 居住於奔流的區域，水質清澈的地方.(高度 200-400 公尺) 不成熟的標本在全流域出現; 成熟的一些顯然地在流動的水中只出現在上游。 觀察的成熟的個體能是藉由跳躍離開水面交叉主要瀑布。 生殖的行為未知。 小標本的主要的胃內容物是軟體動物; 大的標本有小鯉魚的種與果實的骨骼殘骸。 (參考文獻 40416)
