Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 9 - 11; Radios blandos dorsales (total) : 24 - 28; Espinas anales: 3; Radios blandos anales: 26 - 32. Generally silvery overlaid with brassy tones; back bluish or olivaceous; lower head and lower anterior part of body tinged with red; sides with series of brown speckles which form rough narrow vertical bars; pectorals plain, other fins usually reddish (Ref. 6885).
