Espinas dorsales (total): 11 - 12; Radios blandos dorsales (total): 9-11; Espinas anales 3; Radios blandos anales: 7 - 10. Diagnosis: This species is distinguished by the following characters: body oblong moderately and laterally compressed, greatest body depth 2.5-3.2 times in standard length; head length 2.3-2.6 times in standard length; lower opercular spine extending well beyond the opercular flap; posttemporal bone exposed and serrate posteriorly; pectoral fin rays 13-14; gill rakers 6-8 +13-16 = 19-24; pored lateral line scales 75-100; horizontal scale rows above lateral line 13-17; caudal fin emarginate (Ref. 48274, 90102).
Found over shallow sandy bottoms, in the vicinity of river mouths. Enter estuaries and rivers (Ref. 1479, 11230, 44894, 48635), juveniles and adults are often found in freshwater (Ref. 4327). Adults in loose aggregations (Ref. 48635). Juveniles common in sandy intertidal areas; often in tidal pools. Minimum depth reported is 20 m (Ref. 12260). Found in schools (Ref. 9710). Omnivorous (Ref. 7300), feeding on fishes, insects, algae, and sand-dwelling invertebrates (Ref. 9710). Spawn in the sea and juveniles migrate into fresh water (Ref. 2847). Eggs are guarded and fanned by the male parent (Ref. 205). Produce sound (Ref. 9137). Caught on all types of inshore fishing gear including gill nets, traps, handlines, and bottom trawls and marketed fresh and dried-salted (Ref. 48274).
Eggs are guarded and fanned by the male parent (Ref. 205).
