Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 8; Rayons mous dorsaux (Total) : 9 - 10; Épines anales: 3; Rayons mous anaux: 9 - 10. Body very high, 50% of SL. Lateral line incomplete, but a few pored scales on a silvery midlateral band. Lower margin of inter operculum with few spines. The second spine of the first dorsal fin is strong and very long.

Found in brackish-water, mangrove, estuarine and freshwater-stream habitats, usually within 20 km of the sea (Ref. 2847). They occur at temperatures ranging from 28 to 32°C. Found in schools and migrate to freshwater. Mainly diurnal. A predominantly marine or estuarine spawner. Caught by hand and scoop nets (Ref. 7242).
