Etymology: Arnoglossus: Greek, aros, -oy = lamb + Greek, glossa = tongue (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 15 - 300 m (Ref. 5979). Subtropical; 43°N - 6°N, 26°W - 42°E
Eastern Atlantic: Ireland (Ref. 4704) to Sierra Leone and Cape Verde. Also known from the western Mediterranean and Black Sea.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 12 - ? cm
Max length : 18.0 cm SL male/unsexed; (Ref. 4704); common length : 12.0 cm TL male/unsexed; (Ref. 3397); max. reported age: 10 years (Ref. 32766)
soft rays: 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).
