Biology     Glossary (e.g. epibenthic)

Adults are benthopelagic over continental shelves (Ref. 5217). Rare in oceanic insular areas (Ref. 5217). Juveniles associate with the jellyfish Chrysaora lactea in Southwestern Atlantic. Preyed on by juvenile comb grouper (Mycteroperca acutirostris) when protection given by the jellyfish fails (Ref. 52493). Adults are found often in schools. They feed on small invertebrates. Marketed fresh locally and considered a good food fish (Ref. 9626). In southern Brazil, stocks are found in 147 m deep water (Ref. 47377).
