A plain dusky-brown species with a black dorsal fin tip. Shows banded pattern at night. Distinguished from adult Plotosus lineatus by its long barbels on the nostrils that can reach pass the eyes.
一個單色的暗褐色的種具有一個黑色的背鰭頂端。 顯示條紋在晚上。 與成魚 鰻鯰〔Plotosus lineatus〕 區分了用它的長觸鬚在能達到眼的鼻孔上。
Adults found mostly in estuaries and lagoons, and sometimes up rivers in nearly fresh waters. They occur in the lower parts of rivers in freshwater or brackish water and in coastal seas (Ref. 12693, 48635). It is reported to have an extended breeding season and likely spawns in brackish water, based on optimal sperm survival at 0.9 % salinity; produces relatively few large eggs, consistent with parental care and it is possible that male fish construct nests and guard their fry (Ref. 127983), Maximum length of 150 cm TL is without actual specimen (Ref. 3478). Juveniles may occur in dense aggregations (Ref. 9801). Feed on crustaceans, mollusks and fishes. Spines associated with anterior fins have potent venom. Marketed mostly fresh.
大部分發現於河口與潟湖, 而且有時在幾乎淡的水域中提高河。 出現於河的下面部份在淡水中或半淡鹹水與在沿岸海洋中.(參考文獻 12693,48635) 稚魚可能出現在密集的群集。 (參考文獻 9801) 吃甲殼動物，軟體動物與魚。 市場上大部份生鮮地銷售。 連接前面的鰭有強力的毒液的棘。
