Etymology: Chauliodus: Greek, chaulios, chaulos, chaunos = to be with the mouth opened + Greek, odous = teeth (Ref. 45335).
Eponymy: The succession of Danish research vessels named ‘Dana’ seem to have been greatly favoured by describers of fish, and often the etymology includes: “…from which the holotype was collected. [...] (Ref. 128868), visit book page.
