Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 13 - 16; Épines anales: 0; Rayons mous anaux: 13 - 17. Diagnosis: body elongate; lower jaw forming long, narrow beak; upper jaw short, triangular and scaled; scales on snout; well developed preorbital crest between eye and nasal pit; pelvics fin abdominal; dorsal and anal fins placed far back on body and spineless; caudal fin slightly forked (Ref. 57227).
Occurs in coastal waters. Often enters estuaries (Ref. 2683). Live on or near the bottom where it feeds on algae and organic debris which it gathers from the surface of the sediment (Ref. 5377). Forms schools. Attracted to lights at night. Eggs are attached to aquatic vegetation by sticky threads (Ref. 6730).
