Comments: Occurs in brackish estuaries and adjacent marine areas; penetrates freshwater (Ref. 5217).  Forms moderate schools.  Usually migrating from estuaries or the sea, but possibly the <i>limnichthys</i> of Lake Maracaibo and the <i>amazonensis</i> represent purely freshwater forms.  In freshwater, it feeds principally on small fishes, prawns and copepods; also insect larvae.  At sea, it feeds on fishes and various crustaceans.  Spawns in freshwater.  Year round occurrence of eggs reported.
