Descripción breve
Claves de identificación | Morfología | Morfometría
Body compressed; head flat; first dorsal fin with 7 spines, second with 1 spine and 8 to 9 rays; anal fin with 1 spine and 9 to 10 rays; lateral line with 30 to 34 scales; body depth contained about three times in standard length; body dark green to dark brown with numerous small pale spots (Ref. 55763).
Body shape (shape guide): fusiform / normal.
Facultative air-breathing (Ref. 126274); Adults inhabit estuaries, stagnant ditches or creeks of low current velocity between the sea and an elevation of 30 m. Benthic and most abundant on sandy and muddy bottoms. They ingest much mud and detritus, although also filter plankton (Ref. 36880). Found in shallow inshore areas; typically in freshwater but moves freely into the sea.
