Diagnosis: body short and deep (depth comprised 1.8-2.5 times in fork length); snout rounded; mouth small; maxillary reaching to below hind margin of pupil; 2 dorsal fins, 1st with 6 spines, 2nd with 1 spine and 19-21 soft rays; anal fin with 2 short, detached spines followed by 1 spine and 16-18 soft rays; soft dorsal and anal fin lobes shorter than head; pectoral fins short; scales small, cycloid and partially embedded in skin; lateral line very slightly arched over pectoral fins, without scutes; no distinct spots or other colour marks on body (Ref. 57392).
Coloration: back bluish-grey or greenish, sides silvery, without distinctive markings; fins dark; lobes of dorsal, anal and caudal fins darker to black (Ref. 57392).
Adults inhabit coastal waters (Ref. 2683). Enters brackish waters for reproduction and ascends rather far up the lower courses of rivers (Ref. 4225, 57392). Feeds on fish, shrimps, crabs and bivalves (Ref. 28587). Maximum fork length recorded was 610 mm (Ref. 57392).
