Dorsal spines (total): 10; Dorsal soft rays (total): 11; Analspines: 3; Analsoft rays: 10; Vertebrae: 23

Found on the continental shelf and continental slope (Ref. 75154). Associated with rocky habitats and known from 80 to more than 100 m depth but probably also occurring in shallower water, especially as juveniles (Ref 5403). A carnivore (Ref. 9137). Attains 32 cm TL (Ref. 58472).

Associated with rocky habitats and known from 80 to more than 100 m depth but probably also occurring in shallower water, especially as juveniles (Ref.5403). From dive observations, juveniles and young individuals likely occur at 5-30 m depths (Ref. 94109). Eggs are pelagic (0.75 mm), small and spherical.
