seewasser benthopelagisch; standorttreu; tiefenbereich 16 - 1000 m (Ref. 1371), usually 90 - 700 m (Ref. 1371). Subtropical; 59°N - 24°N, 81°W - 42°W (Ref. 1371)

Northwest Atlantic: Newfoundland, Canada to the northern end of the Straits of Florida, USA. A species reported from the northeastern Atlantic (Ref. 6321) should be reexamined. Report of specimen from the Azores and records from the Gulf of Mexico and West Indies (Ref. 6322) probably refer to other species.

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Benthic, reported as deep as 2295m (Ref. 58426). Taken much shallower in areas with cold surface waters. Feeds primarily on euphausiids, amphipods, and polychaetes, although a 200 mm individual had many copepods in its stomach (Ref. 1371).
