Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 14 - 16; Spine anali: 3; Raggi anali molli: 8 - 10. Head spines weak - nasal, preocular spines present, parietals usually present, supraocular, postocular and tympanic spines usually absent, coronal and nuchal spines absent (Ref. 27437). Interorbital space convex, sloped; no symphyseal knob; caudal peduncle narrow; anal fin with a strong posterior slant (Ref. 27437). Caudal fin indented (Ref. 6885). Gold brown to dusky, light ventrally; membranes of fins dark, lighter on spinous dorsal (Ref. 27437).
Body shape (shape guide): fusiform / normal.
A generally active and free-swimming rockfish found in midwater above a rocky reef or steep shoreline; occasionally huddling motionless among caves and crevices (Ref. 27436). Young are found in shallow water (Ref. 2850). Form schools (Ref. 2850). Feed mostly on small pelagic crustaceans and fishes (Ref. 2850). Viviparous (Ref. 34817). Marketed fresh and frozen; eaten pan-fried, boiled, microwaved and baked (Ref. 9988).
