Biologi     Daftar kata (contoh epibenthic)

Found on continental shelves, often on sandy beaches and rarely in estuaries (Ref. 244). Reported to enter freshwater and recorded several times from Cambodia as far upstream as the Great Lake (Ref. 12693). Occurs near the surface in shallow waters (Ref. 12693). Feeds mainly on small pelagic and benthic bony fishes, also cephalopods and other invertebrates (Ref. 244). Viviparous (Ref. 50449). Utilized fresh and possibly dried salted for human consumption and for fishmeal (Ref. 9997). The 178 cm specimen recorded off Africa is possibly based on some other species (Ref. 9997).
