Length at first maturity / Size / Peso / Age
Maturità: Lm 37.8, range 28 - 50 cm
Max length : 66.0 cm TL maschio/sesso non determinato; (Ref. 56527); common length : 44.1 cm TL maschio/sesso non determinato; (Ref. 56476); peso massimo pubblicato: 550.00 g (Ref. 56476); Età massima riportata: 10 anni (Ref. 56527)
Spine dorsali (totale) : 2; Spine anali: 0. Snout short, blunt, with a broad spinous scute at its tip, its leading edge and most of its underside naked; suborbital shelf very narrow anteriorly; interopercle broadly rounded posteriorly; chin with very short barbel. Scales rather deciduous; body scales with 3 to 10 low, subparallel rows of spinules; gill and gular membranes and interopercle naked. Pyloric caeca short, 5 to 7. Overall color is grayish brown; fins blackish to dusky; oral and gill cavities blackish.
Body shape (shape guide): elongated; Cross section: circular.
Feeds mainly on pelagic forms (Ref. 1371). Too small for fresh consumption (Ref. 1371).
