Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL maschio/sesso non determinato; (Ref. 57392); common length : 30.0 cm TL maschio/sesso non determinato; (Ref. 2683)
Spine dorsali (totale): 7; Raggi dorsali molli (totale): 20-23; Spine anali 3; Raggi anali molli: 18 - 21. Diagnosis: body short and deep (its depth 1.8-2.6 times in fork length), lozenge-shaped and strongly compressed; front of head arched; snout rounded; upper jaw extending almost to below hind margin of eye; 11-13 gill rakers on lower limb of first gill arch; 2 dorsal fins, 1st with 6 spines, 2nd with 1 spine and 20-23 soft rays; anal fin with 2 short, detached spines followed by 1 spine and 18-21 soft rays; lobes of soft dorsal and anal fins strongly developed and falcate, longer than head at sizes over 10 cm; pectoral fins shorter than head; scales small, cycloid and partially embedded in skin; lateral line scarcely arched over pectoral fins, without scutes; 4-6 black spots distributed all along lateral line (Ref. 57392).
Coloration: back greenish, sides silvery, with 4-6 (usually 5) dark spots regularly spaced along lateral line, 1st as a vertical line, others oval to circular and becoming progressively smaller backwards; dorsal- and anal-fin lobes dark, caudal fin dark, but light-edged distally; these spots absent or indistinct in juveniles smaller than 100 mm (Ref. 57392).
Coastal marine species (Ref. 2683, 57392) occurring down to 100 m depth (Ref. 57392), frequently entering estuaries (Ref. 2683, 57392) and ascending lower courses of rivers (Ref. 57392). Maximum length possibly up to 100 cm (Ref. 57392).
