Remarks | 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). Feeds on benthic organisms (clams, mysids and small crangonids; Ref. 434). Also occurs in pelagic depths between 100 to 200 m (Ref. 92299). Opportunistic predator (Ref. 112170). |
