Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Adults are common near the edge of the continental and island shelves; also found in deeper waters (below 200 m); usually ascending to shallow water at night. They feed mainly on fishes, shrimps, crabs, gastropods, cephalopods, tunicates and some pelagic items including urochordates. Marketed fresh. Said to be a good food fish (Ref. 5521).

Spawning occurs over most of the year in lower latitudes, but is seasonal (spring and summer) toward the northern and southern limits of the distribution.
