Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL maschio/sesso non determinato; (Ref. 11035)
Spine dorsali (totale) : 11; Raggi dorsali molli (totale) : 16 - 18; Spine anali: 3; Raggi anali molli: 8. Distinguished by the following characteristics: olive green to reddish brown with scattered irregular white and brown spots and blotches; white triangle at the margin of the interspinous dorsal-fin membranes and bright white tag at the tip of each spine; juveniles with black spots on the top of head and median fins reddish distally with white edge; small black saddle on peduncle; inside of mouth is red; depth of body contained 2.7-3.1 times in SL; head length 2.2-2.5 times in SL; flat interorbital area; rounded preopercle, finely serrate, slightly enlarged ventral serrae; smooth subopercle and interopercle; slightly convex upper edge of operculum; subequal anterior and posterior nostrils (Ref. 89707).
Adults are most abundant in shallow water and also occurs to a depth of at least 30 m. Inhabits rocky area of coastal waters within continental shelf (Ref. 11035). A solitary predator that seems to feed on smaller fishes by day and crustaceans after dark. Spawning occurs in late summer (Ref. 5592).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00982 - 0.02557), b=3.04 (2.91 - 3.17), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.66 se; based on food items.
Generation time: 5.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
