腹面有 23 或者 24+8 到 11, 總計 33 或 34個鱗甲。 下頜突出的; 上頜有在前顎骨與顎骨葉片的低凸起的後部頂端之間的一個有齒的皮下注射-上頜骨的硬骨; 下鰓耙 12 到 14.(在 20 到 50 公分標準長度的魚中) 腹鰭有一個明顯的腋窩鱗片; 臀鰭長的, 在背鰭基底下面的它的起源。 鱗片非常小的。
Occurs in rivers, apparently not entering the sea, although presumably tolerating at least some salinity at the Amazon mouth. More data needed.
出現於河, 顯然地不進入海洋, 雖然可能在亞馬遜河嘴容忍至少一些鹽度。 需要更多的資料。
