Highighted items on the list are where Trichiurus lepturus may be found.
Remarks Generally over muddy bottoms of shallow coastal waters (Ref. 9351). Often enter estuaries (Ref. 9351). Adults and juveniles have opposing complementary vertical diurnal feeding migration. Juveniles and small adults form schools about 100 m above the bottom during daytime and form loose feeding aggregations at night-time near the surface where they prey on planktonic organisms such as euphausiids, small pelagic planktonic crustaceans and small fishes (anchovies, bregmacerotids, etc.). Large adults feed on pelagic prey (anchovies, sardines, myctophiids, bregmacerotids, carangoids, sphyraenids, atherinids, sciaenids, Scomber, Trichiurus, squid and crustaceans, etc.) near the surface during daytime and migrate to the bottom at night. One of the main predators during summer in a sandy beach at Canto Grande, Santa Catarina, Brazil (Ref. 55758).
