Actinopteri (ray-finned fishes) > Lophiiformes
(Anglerfishes) > Gigantactinidae
Etymology: Gigantactis: Greek, 'gigas' or 'gigantos' = gigantic + Greek, 'aktis' = ray (referring to the unusually long first dorsal-fin spine that functions as a lure in this genus) (Ref. 86949).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 465 - 1640 m (Ref. 86949). Deep-water
Atlantic Ocean: a single record is known from the Gulf of Guinea and another record is known from the northwest Atlantic.
