Maturity: Lm ?  range ? - ? cm
Max length : 60.0 cm TL male/unsexed; (Ref. 11035)
soft rays: 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).
