Description

The angular roughshark is a remarkable, stocky deep-sea shark of the family Oxynotidae reaching about 150 cm. The body is high and almost triangular in cross-section, with two large, sail-like dorsal fins each bearing a spine, and a very rough, abrasive skin. The colour is uniform grey to grey-brown. The species lives on the outer continental shelf and upper slope of the eastern Atlantic and Mediterranean and is a suction feeder that mainly takes worm-like prey such as polychaetes. Because of heavy fishing and slow reproduction the angular roughshark is assessed as Endangered across its range.
