The angular roughshark, Oxynotus centrina, is a rough shark of the family Oxynotidae. They occur in the eastern Atlantic from Norway to South Africa, including the entire Mediterranean. The angular roughshark has a compressed body, triangular in cross section, with a broad and flattened head. The snout is flat and blunt. Just like all of the Oxynotus species, they have two relatively large dorsal fins that are sail-like and no anal fin. Their color scheme is grey or grey-brown dorsally with dark blotched on its head and sides. However, one identifying feature is the light horizontal line below the eyes on the cheek.
