بوم شناسي
دريايي ناحیه ای از منطقه اقیانوسی با عمق بین 1000 تا 4000 متر. موجوداتی که در آبهای آزاد بین اعماق 1000 تا 4000 متر زندگی و تغذیه می کنند; اقیانوس رو (Ref. 51243); تغييرات عمق 50 - 2500 m (Ref. 26165), usually 500 - 600 m (Ref. 4775). Deep-water; 50°N - 50°S, 180°W - 180°E
Circumglobal in tropical and temperate waters, but with a distinct equatorial gap in the Pacific (Ref. 9835). Western Atlantic: Canada to Brazil. Eastern Atlantic: Morocco to Mauritania and from Liberia to Namibia (absent in Mauritanian Upwelling Region). Indian and Pacific: confined to southern equatorial water masses, extending to 50°N and 50°S in western boundary currents. South China Sea (Ref.74511).
