Biologi     Ordlista (t.ex. epibenthic)

Form schools. They occur frequently near the bottom, mostly in depths of 30 to 50 m. Also pelagic and found near the surface at times. Entering brackish-water lagoons and estuaries (Ref. 57392). Feed on small fish and invertebrates (Ref. 3195). Spawning grounds are located in shallow waters (Ref. 57055). Eggs are pelagic (Ref. 4233).
