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).

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 5; 臀棘: 0; 臀鰭軟條: 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).
變態的雌性不同於所有的其他 Gigantactis 同類有誘餌 330% SL 的長度; 餌球幾乎圓球狀, 具有一個短,截形的末梢部的延伸,末梢部地有顏色, 而且生長著兩對的短，竹片狀的附肢; 沒有絲狀突起的誘餌的莖; 齒骨齒短 (長的牙齒 1.7% SL),在後部地在二縱向的系列中安排; 長的尾部鰭條 50% SL.(參考文獻 41361)
Known only from the holotype collected in an open midwater trawl (Ref. 41361). Maximum length based on an immature female (Ref. 41361).
所知僅來自正模標本在一個開放的中層水域拖網收集了.(參考文獻 41361) 最大的長度以一個不成熟的母魚為依據.(參考文獻 41361)
