Biologia     Glossário (ex. epibenthic)

A schooling species (Ref. 5217, 57391) generally not far from the coast (Ref. 5217), in coastal marine and brackish waters to at least 100 m depth (Ref. 57392). Juveniles often found in association with floating Sargassum (Ref. 5217), often entering lagoons and estuaries (Ref. 57392). Adults feed on fishes, shrimps, and other invertebrates. They spawn offshore from January through August (Ref. 26938). Eggs are pelagic (Ref. 4233). Excellent food fish (Ref. 9626); marketed fresh, frozen (Ref. 5521), and salted. Often used for bait (Ref. 26938). Maximum reported total length 550mm in Ref. 57392.
