| Main Ref. | Fischer, W., M.-L. Bauchot and M. Schneider (eds.), 1987 |
|---|---|
| Remarks | Occur in inshore waters of the continental shelf and continental slope (Ref. 75154). Adults prefer to inhabit caves and shipwrecks (Ref. 27121). Juveniles congregate below floating objects (Ref. 27121). Usually solitary. Young somewhat gregarious, epipelagic, often below floating wreckage. Feed on large crustaceans, cephalopods and benthic fishes (Ref. 27121); also other benthic invertebrates (Ref. 231). |
