Biologia     Glossario (es. epibenthic)

Found over sand or mud bottoms from the coastline to about 60 m depth (Ref. 3702); rarely in waters with a depth of less than 18 m (Ref. 9626). Juveniles inhabit river estuaries (Ref. 3702). Oviparous, with high fecundity (Ref. 54358). Feed on fishes and crustaceans like crabs and shrimps (Ref. 35237). Important food fish (Ref. 3702).
