Etymology: Himantolophus: Greek, himas or himantos = leather strap, thong or leash (referring to the thick leathery illicium) + Greek, lopho or lophio = crest or tuft (referring to the baited illicium projecting from the head) (Ref. 86949); borealis: From the Latin borealis meaning northern (Ref. 43997)
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 1210 - m (Ref. 43997), usually - m (Ref. ). Deep-water; 0°C -
