Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 114 cm TL maschio/sesso non determinato; (Ref. 89707); peso massimo pubblicato: 22.3 kg (Ref. 40637)
Spine dorsali (totale) : 10; Raggi dorsali molli (totale) : 16 - 18; Spine anali: 3; Raggi anali molli: 8. Distinguished by the following characteristics: generally pale reddish brown covered with numerous dark brown spots; 5 faint oblique dark bars on body; body depth less than head length, 2.6-3.0 times in SL; head length 2.3-2.5 times in SL; shallow notch above the angle of preopercle, serrae at angle slightly enlarged; slightly convex upper edge of operculum; subequal posterior and anterior nostrils; pelvic fins shorter than pectoral fins and their origin below or behind lower end of pectoral fin base; rounded caudal fin; ctenoid midlateral-body scales, with numerous auxiliary scales (Ref. 089707).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Abundant in patch reefs where it is readily caught by anglers. Inhabits depths of at least 50 m (Ref. 089707). Feeds mainly on crustaceans and fishes on rocky and sandy bottoms. During winter, it moves closer to the shore where it feeds heavily on swarms of pelagic red crab Pleuroncodes planipes.
