Short description

Dorsal spines (total): 0; Anal spines: 0. Chin barbel well developed. Pelvic fins with slightly elongated anterior rays. Body light brown dorsally, relatively tall, grayish on the sides becoming silvery ventrally, with four or five broad indistinct transverse bars on the sides; a dark blotch at the upper edge of the pectoral-fin base (Ref. 1371). Eye diameter as snout length. Anus lies below the middle of the first dorsal fin (Ref. 35388).

Gregarious fish; immature ones often occur in large schools. Lives mostly on the outer shelf, but moves inshore to depths of 50 m or less for spawning. Feeds on benthic crustaceans but also on small fish, mollusks and polychaetes (Ref. 3663). Caught as a bycatch, used as food fish (Ref. 35388).
