Sides silvery with numerous round brownish (orange in life) spots, three rows above lateral line, one above. The first dorsal fin is black distally and white at the base. The second dorsal fin is tinged with yellowish and with black margin. The anal fin is white.
A schooling species believed to spawn close to the coast over most of its range. Adults occur near the surface of coastal waters to over bottom of the continental shelf (Ref. 11035). Adults feed on small fishes, particularly anchovies (Anchoa and Cetengraulis) and clupeids (Odontognathus and Opisthonema). The most abundant game fish along the Pacific coasts of Mexico and Central America. An excellent food fish enough to support a commercial fishery. Marketed fresh and frozen; also used for ceviche (Ref. 9987).
