Biologie     Verklarende woordenlijst (bv. epibenthic)

Adults are found mainly over the continental shelf, often over sand bottoms (Ref. 27121). Shoals rise to feed in surface waters at night and found close to the bottom during the day (Ref. 27121). Juveniles feed mainly on copepods while adults prey on fish and a wide range of invertebrates (Ref. 27121).
