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).
Eponymy: Dr Jay Mathers Savage (d: 1928) is an American herpetologist and educator who is known particularly for his work on the herpetofauna of Central America. [...] (Ref. 128868), visit book page.
