> Lophiiformes (Anglerfishes) > 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: These species are named after the research vessel ‘Walther Herwig’, from which all the holotypes were caught. The vessel was named after Walther Herwig (1838–1912), who is regarded as the founder of German fisheries science. (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 5.9 - 16.5, mean 10.5 °C (based on 103 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (22 of 100).
