Short description Morfología | Morfometría

Espinas dorsales (total): 9; Radios blandos dorsales (total): 10; Espinas anales 3; Radios blandos anales: 7. Body silvery with 6-8 irregular, faint dusky oblique and vertical bands dorsolaterally and ventrolaterally (usually more apparent in young stressed or preserved specimens. U-shaped premaxilla groove mostly without scales (tiny scales anteriorly in specimens over 13 cm SL). Posterior margin of maxillary beyond a vertical through anterior margin of pupil. Supraneural bones 3. Spinous dorsal fin with an indistinct dusky patch (2nd-6th spines) and very narrow dusky distal margins on upper membranes between spines. Scales between 5th dorsal fin spine and lateral line 3-4, usually 3.5. Pelvic fin when fresh is semi-transparent or dull yellow color with an indistinct dusky band and dull white distal margin posteriorly (Ref. 35850); pectoral fins reaches beyond level of anus; caudal fin forked deeply and with long lobes (Ref. 90102).
