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

Common in bays and estuaries often entering rivers. Also found in offshore waters at depths of about 500 m, generally less than 100 m. Feeds mainly on small bony fishes, including wrasses, but also marine snails, squid and shrimp. Viviparous, with 2 to 6 young in a litter. Size at birth about 31 to 39 cm. Utilized salted or frozen for human consumption and processed into fish meal. Not dangerous (Ref. 9710).
