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.
身体宽度 14.9-17% SL; 前背的长度 34.6-36.1% SL。 大的犁骨齿碟与长且细的上颚齿板接壤了。 一 2-腔室的泳鳔局限于腹部了。
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).
采集自淡水的河口附近了; 居住于在海洋附近的大的水池,藉由深的而且浑浊的水域。 在上游中, 居住于奔流的区域，水质清澈的地方.(高度 200-400 公尺) 不成熟的标本在全流域出现; 成熟的一些显然地在流动的水中只出现在上游。 观察的成熟的个体能是藉由跳跃离开水面交叉主要瀑布。 生殖的行为未知。 小标本的主要的胃内容物是软件动物; 大的标本有小鲤鱼的种与果实的骨骼残骸。 (参考文献 40416)
