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). Eponymy: IOS stands for the Institute of Oceanographic Sciences, England, which supplied the type specimen of the hagfish. [...] (Ref. 128868), visit book page.
