Short description

Dorsal spines (total): 5; Dorsal soft rays (total): 37-41; Anal spines: 3; Anal soft rays: 20 - 24. Dark brown to black, occasionally almost bluish; median and pelvic fins darker than body; young with 2-4 vertical bars (Ref. 4410). Snout is slightly longer than the eye diameter (Ref. 35388).
