Max length : 50.0 cm TL mâle / non sexé; (Ref. 55); common length : 30.0 cm TL mâle / non sexé; (Ref. 55); âge max. reporté: 40 années (Ref. 2290)
Épines dorsales (Total) : 10; Rayons mous dorsaux (Total) : 14; Épines anales: 3; Rayons mous anaux: 8. Snout somewhat pointed. Preopercular notch and knob moderately well developed. Scale rows on back rising obliquely above lateral line. Generally pale blue-gray to whitish with suffusion of yellow on upper back. A prominent golden brown stripe, slightly narrower than the eye, runs laterally from the rear edge of the of the opercle to the caudal peduncle.
