Short description

Dorsal spines (total): 10; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 9 - 10. Eye is relatively large, its lower edge well above a line from the tip of the snout to the middle of the caudal fin fork. Caudal fin is moderately forked and with blunt tips. Overall color is silvery white to grayish. The scales of the back and sides have a small brownish basal spot. Prominent black blotches are scattered mainly on the anterior half of the body. A very faint bar is sometimes present below the eye to the lower edge of the cheek. Fins are clear to reddish, the caudal fin sometimes dusky reddish-brown. Faint spots may be evident on the dorsal, caudal, and anal fins.

Occurs over sand and rubble areas adjacent to rock and coral reefs. Feeds on bottom-dwelling gastropods. Also caught with bottom longlines and handlines (Ref. 9775). Marketed fresh.
