Etymology: Peristedion: Greek, peri = around + Greek, stethion = breast.
Environment / Climate / Range
Marine; demersal; depth range 50 - 848 m (Ref. 56504), usually ? - 150 m (Ref. 10780). Deep-water; 52°N - 15°S, 18°W - 36°E
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 22 - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 3397); common length : 18.0 cm TL male/unsexed; (Ref. 3397)
Eastern Atlantic: British Isles and English Channel to Angola, including the Mediterranean.
Depth range from 50-600 m (Ref. 10780) and from 288-848 m in the eastern Ionian Sea (Ref. 56504). Gregarious. Occurs on muddy or rocky bottoms of the shelf. Digs the mud with its rostrum, searching for prey; stands and walks on the bottom with its free pectoral rays. After a pelagic existence, the juveniles live in coastal waters before migrating to deeper waters (Ref. 6556). Minimum depth range taken from Ref. 27000.
