Short description

Dorsal spines (total): 10 - 11; Dorsal soft rays (total): 13-14; Anal spines: 3; Anal soft rays: 7 - 8. Preopercular notch and knob weak. Pectoral fins long reaching level of anus. Scale rows on back rising obliquely above lateral line. Back and upper sides pink to red, grading to pink with a silvery sheen ventrally; sides with very fine undulating yellow lines; the fins mostly reddish or pale yellow. Young specimens (under about 25 cm) with a blackish spot on upper side below anterior dorsal soft rays.

Adults are common near the edge of the continental and island shelves; also found in deeper waters (below 200 m); usually ascending to shallow water at night. They feed mainly on fishes, shrimps, crabs, gastropods, cephalopods, tunicates and some pelagic items including urochordates. Marketed fresh. Said to be a good food fish (Ref. 5521).
