The angular roughshark, Oxynotus centrina, is a rough shark of the family Oxynotidae.

Biologist Carl Linnaeus describeded the angular roughshark, O. centrina, in 1758. This name was later finalized and accepted by the scientific community as the official name for the species in 1976.

At birth, they are less than 25 cm (9.8 in) and they mature at about 50 cm (20 in). Most records are of individuals less than 1 m (3.3 ft), but they can reach about 1.5 m (4.9 ft). Their litter size is seven or eight pups off Angola to 23 in the Mediterranean. They have ridges over their eyes that expand into large, rounded knobs, which are covered with enlargeddenticles – these are absent in other species of rough sharks. They possess very large spiracles that are vertically elongated, being almost as high as the length of their eyes. Their first dorsal spine is oriented slightly forward. They feed on worms, crustaceans, and mollusks. source
