Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 9; Radios blandos dorsales (total) : 10 - 11; Espinas anales: 3; Radios blandos anales: 7. Silvery in color but olive brown above; brown stripes following scale rows above lateral line and the 4 rows below it; spinous dorsal fin with black margins (Ref. 4372). Squamation pattern on the preopercular flange 5-17 scales (Ref. 41102).
Body shape (shape guide): short and / or deep.
