Restricted to high islands (Palau, Caroline and Mariana islands) in Micronesia. Reported as far inland as the lower Shire in Malawi and the Save-Runde junction in Zimbabwe (Ref. 7248, 52193). Widespread in the Lower Zambezi River channels up to Marromeu and in the Micelo River up to Malingapanzi (Ref. 39494). South China Sea, Taiwan Strait, and East China Sea(Ref.33302).

Obligate air-breathing (Ref. 126274); Adults are generally found at sea, but young inhabit river mouths, inner bays, and mangrove forests. In freshwater, they occur in rivers, lagoons, lakes, and swampy backwaters (Ref. 2847, 44894). Tolerate a wide pH range (5.2-9.1) (Ref. 44894) and salinities from 0 to 100. Mainly diurnal (Ref. 7017). Predaceous, feeding mainly on fishes and crustaceans (Ref. 5213). Breed offshore, possibly throughout the year. Larvae are transparent and resemble larval eels (Ref. 13337), but with a forked tail (Ref. 167). Juveniles commonly enter freshwater (Ref. 44894, 48635) in clear or turbid water (Ref. 44894). Known to breath air, rising regularly to the surface to do so. Cultured in ponds, the fry being sourced from the coasts (Ref. 7050). Popular angling fish (Ref. 3969). Edible but not esteemed (Ref. 3969). Caught by gill nets, seines, and trawls, and by hook-and-line; marketed fresh and dried salted (Ref. 10982).
成鱼是通常发现于的海洋，但是幼鱼居住于河口，海湾内与红树林森林。 在淡水中，它出现于河，舄湖，湖与沼泽的洄水区中。 (参考文献 2847,44894) 容忍宽的酸碱度范围 (5.2-9.1)(参考文献 44894) 与盐度从 0 到 100 。 主要日行性.(参考文献 7017) 食肉的, 主要捕食鱼与甲壳动物.(参考文献 5213) 繁殖外海, 可能地全年度。 仔鱼是透明的而且与幼虫的鳗鱼相似。 (参考文献 13337) 稚鱼通常在清澈或混浊的水进入淡水 (参考文献 44894,48635) 。 (參考文獻 44894) 已知了呼吸空氣, 經常地對表面升起這麼做。 養殖在距離海岸被來源的池塘，魚苗中了。 (參考文獻 7050) 受歡迎的垂釣魚種.(參考文獻 3969) 可食用的但是不讚賞.(參考文獻 3969)
