Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 10 - 12; Mjukstrålar i ryggfenan (totalt) : 18 - 20; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 13 - 16; Ryggkotor: 35. Dorsal with moderate notches in the spinous part after the third spine, and between the spinous and rayed parts; caudal bluntly rounded; pelvic fins larger in males (Ref. 6885). Color variable, predominately red, sometimes brilliant red, with brown, white, and black mottling and spotting all over; there are four irregular dark saddles across back; the caudal fin with darker rays, sometimes with vertical light bars; some large males with darkly spotted pelvic fins (including base of pectorals) (Ref. 6885).
Body shape (shape guide): elongated.
Usually near shore in rocky areas (Ref. 2850), from intertidal areas to 275 m depth (Ref. 6793). Adults feed on crabs, barnacles, and mussels (Ref. 6885). Good eating (Ref. 2850).
