Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 14 - 17; Épines anales: 0; Rayons mous anaux: 19 - 26. Body moderately elongate and compressed (Ref. 189). Snout short, about 2/3 eye diameter; maxilla relatively long, tip bluntly rounded, reaching to pre-operculum; gill cover canals of walkeri-type (Ref. 189). Anal fin fairly long, its origin below about middle of dorsal fin base. A broad silver stripe along flank, equal or greater than eye diameter below dorsal fin (Ref. 189).

A schooling species found inshore. Most likely anadromous, entering estuaries and freshwater. Feeds on crustacean larvae or small invertebrates (Ref. 12225). Female maximum length from Ref. 71685.
Both sexes at maturity have a large amount of visceral and intermuscular fat (Ref. 189). Spawn in school (Ref. 205).
