Etymology: Arnoglossus: Greek, aros, -oy = lamb + Greek, glossa = tongue (Ref. 45335).
Eponymy: These genera and species are named after ‘Thor’, the first Danish research vessel specifically equipped for oceanic scientific research (named after the Norse god of thunder). [...] (Ref. 128868), visit book page.

Espinhos dorsais (total) : 0; Raios dorsais (total) : 81 - 91; Raios anais : 61 - 69. Second ray of dorsal fin very long, with a conspicuous dark, fringed broad membrane. First 3 or 4 dorsal fin rays generally blackish in adults but only the elongate second ray is dark in immature fishes.
Found on the upper 100 m of the continental shelf. Feeds on small fishes and invertebrates (Ref. 4704). Minimum depth reported taken from Ref. 52678 but has been caught in depths inferior to 10m (Ref. 57407).
