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); cheni: Named for Mr. Din-Moo Chen, who is an excellent fisherman and who collected most
samples, including the type series of both the new species in this reference.
Eponymy: Din-Moo Chen is described in the etymology as an excellent fisherman who collected (off northeast Taiwan) most samples for the authors’ studies, including the type series of both new species in the publication which included the eponymous species [...] (Ref. 128868), visit book page.

Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 6; Anal soft rays: 6. This species which is a member of the Gigantactis vanhoeffeni species group differs from its congeners in having a single row of 8-15 unpigmented filaments on the posterior margin of basal one-third of illicium; illicial length 145.5-172.1% SL; esca is elongated, tapering into a conical shape, with numerous spinules, darkly pigmented; distal prolongation length 10.6-12.6% SL; dentary teeth 66-70 on each side, in 5 longitudinal series; dentary teeth relative long, 2.5-3.4% SL; caudal fin rays are short, 25.5-30.6% SL; caudal fin deeply forked (Ref. 122006).
