Gigantactinidae (Whipnose anglers)
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); longicauda: From the Latin longus, for long, and cauda for tail, in reference to the deeply cleft caudal fin and elongate caudal fin rays (Ref. 41361).

Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Các tia vây lưng cứng (tổng cộng) : 0; Các vây lưng mềm (tổng cộng) : 5; Tia cứng vây hậu môn: 0; Tia mềm vây hậu môn: 5. Metamorphosed females differ from all other Gigantactis congeners in having length of illicium 330% SL; escal bulb nearly spherical, with a short, truncated distal prolongation, pigmented distally, and bearing two pairs of short, spatulate appendages; stem of illicium without filaments (Ref. 41361); short dentary teeth (longest tooth 1.7% SL), arranged posteriorly in two longitudinal series; longest caudal fin rays 50% SL (Ref. 86949).
Known only from the holotype collected in an open midwater trawl (Ref. 41361). Maximum length based on an immature female (Ref. 41361).
