The angular roughshark (Oxynotus centrina) is a rough shark of the family Oxynotidae.
They have ridges over their eyes that expand into large, rounded knobs, which are covered with enlarged denticles – these are absent in other species of rough sharks.
[3] Oxynotus centrina has a compressed body, triangular in cross section, with a broad and flattened head.
[5] Oxynotus centrina usually moves by gliding on the bottom of the sea, sometimes hovering over the sandy or muddy surfaces of the seabed.
The shark exhibited partial pigmentation reduction, resulting in a pale appearance with white-greyish patches.
Classified as leucistic, this case represents the first documented instance of leucism in the species and the first color disorder reported in the family Oxynotidae.
[4] Oxynotus centrina is a bathydemersal shark typically found on the outer continental shelves and upper slopes of the eastern Atlantic,[4] ranging from Norway to South Africa and throughout the entire Mediterranean, with additional occurrences reported off the coast of Mozambique.
However, recent studies, conducted by Lipej in 2004, show that some juveniles have been caught in the central Adriatic.
[1] However, this species was absent in the northeast Atlantic in a study of deepwater longline fishing for sharks near the Canary Islands.
