This species is distinguished by having the following set of characters: fully scaled breast; naked cheek; anteroventral profile of lower jaw is almost straight; a distinct, jet-black blotch distally on the spinous dorsal fin (Ref. 74926).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Dorsal spines (total): 8; Dorsal soft rays (total): 16; Analspines: 3; Analsoft rays: 14

Found on shallow waters near the bottom. Young enter brackish waters (Ref. 4833). Feed mainly on small crustaceans, foraminiferans and nematodes.
