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: Kai L Elsman was a scientific illustrator, particularly of ichthyological and entomological subjects. The etymology says: “This species is named for the late Kai L. Elsman, whose superb illustrations have added immeasurably to this revision.” (Ref. 128868), visit book page.
