Dorsal spines (total): 0-0; Dorsal soft rays (total): 13-14; Anal spines: 0-0; Anal soft rays: 21-28. Depth widely variable. Snout about 2/3 eye diameter; maxilla moderate, pointed, reaching onto sub-operculum. Gill rakers short, the longest not less than pupil diameter in adults. Dorsal fin origin behind midpoint of body; anal fin origin below 6th-8th branched dorsal fin rays. Silver stripe up to twice eye diameter at widest, lost in fishes over 10 cm SL.

| 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 limnichthys of Lake Maracaibo and the amazonensis 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. |
