Lunghezza alla prima maturità / Dimensione / Peso / Età
Maturità: Lm ?, range 86 - ? cm
Max length : 137 cm SL maschio/sesso non determinato; (Ref. 4787); common length : 70.0 cm TL maschio/sesso non determinato; (Ref. 5450); peso massimo pubblicato: 58.6 kg (Ref. 4787)
Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 12 - 14; Spine anali: 3; Raggi anali molli: 8. Distinguished by the following characteristics: juveniles are lavender-grey or pale brownish, shading to white ventrally; 2 black-edged white longitudinal bands, upper band extending from above the eye to the anterior dorsal-fin rays, and the lower band from below the eye to the lower band from below the eye to the lower caudal-fin rays; black spots and streaks on dorsal and caudal fins; head and body of large adults, uniformly grey; body depth contained 2.9-3.4 times in SL; head length 2.3-2.6 times in SL; convex interorbital area, convex dorsal head profile; angular preopercle, 3-7 distinctly enlarged serrae at angle; distinctly convex upper edge of operculum; subequal anterior and posterior nostrils; maxilla reaches past vertical at rear edge of eye; 2-3 rows of teeth on midlateral part of lower jaw (Ref. 89707).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Seems to prefer continental localities; bottoms of low relief. Large individuals are taken on coarse sand or rocky areas, while the smaller ones live on silty-sand and muddy bottom. Also caught throughout the year by long-liners (Ref. 5222).
