Biología     Glosario (por ej. epibenthic)

Usually found over sandy mud bottoms in coastal waters near river mouths (Ref. 3702). Adults stay in deep waters during the day and swim to the surface at night (Ref. 35237). Juveniles inhabit estuaries. Marketed fresh; its flesh is of excellent quality (Ref. 3702). Its swim bladder is being used to make glue (Ref. 35237).
