Occurs mainly on the outer continental shelf and upper slope, recorded up to 500 m. Diet mainly based on crustaceans; juveniles feed on amphipods and carid shrimps while adults feed on prawns and bony fishes (Ref. 114953). Lengths of adolescent males unknown, but largest juvenile male was 23.4 cm TL, adult males 31.5-32.1 cm TL, with smallest juvenile 17.0 cm TL (Ref. 75648).
