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.
