Demersal (Ref. 85316). Maximum depth range from Ref. 114857; minimum common depth from Ref. 80253. Maximum total length (female) from Ref. 104052 Prefers mud or muddy sand substrates (Ref. 8). Juveniles settle at around 100 m, though can be detected up to 300 m, while larger individuals are always found deeper than 350 m (Ref. 80253).
