Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 19; Mjukstrålar i ryggfenan (totalt) : 4 - 5; Taggstrålar i analfenan: 10 - 12; Mjukstrålar i analfenan: 3 - 5. Head and body mottled light to dark brown to deep chocolate brown throughout. Fin membranes greyish brown to black with tips of dorsal and anal fins white or orange. Distinguished from other rockfishes in having 10-12 spines in the anal fin.
