Dorsale stekels (totaal) : 19; Dorsale zachte stralen (totaal) : 4 - 5; Anale stekels: 10 - 12; Anale zachte stralen: 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.
