Benthic species of continental shelf on rocky and sandy bottoms to depths of 150 m. It is a night feeder, mainly on small fishes and prawns (Ref. 114953). Ovoviviparous (Ref. 50449). Maturity size of males at ca. 47 cm TL, females at ca. 45 cm TL. Species born at ca. 18 cm TL. It is a likely bycatch of gillnet and prawn trawl fisheries (Ref. 114953).
