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 Gerhard Krefft (1912–1993) was a German ichthyologist and herpetologist whose great uncle was Johann Ludwig Gerard Krefft (below). [...] (Ref. 128868), visit book page.

Dorsale zachte stralen (totaal) : 7; Anale zachte stralen: 6. Metamorphosed females distinguished by the following characteristics: length of illicium less than 120% SL; distal escal prolongation with spinules at base and several unpigmented, digitiform filaments on lateral margins; absence of escal papillae; posteromedial papilla at base of escal bulb and second on illicium below bulb; absence of proximal escal filaments; dentary teeth relatively long (longest 2.6-5.2% SL), in four or five longitudinal series; rays of caudal fin less than 30% SL (Ref. 86949).
Minimum depth from Ref. 58018.
