Main Ref. Vergara, R., 1978
Remarks Forms large schools over the continental shelf, except during the winter months when it may descend to deeper water. Juveniles are generally found under floating weeds and jellyfish. Often found in brackish waters (Ref. 26938). Nerito-pelagic (Ref. 58426). Adults feeds mainly on jellyfish (Ref. 26938), squids, arrow worms, crustaceans and worms (Ref. 58426), also fish, benthic invertebrates and plankton (Ref. 2702). Preyed upon by haddock, silver hake, bluefish, weakfish and swordfish, Xiphias gladius. Parasite found was a monogenean, Microcotyle poronoti (Ref. 5951).
