Description
The thornback ray is a flat cartilaginous fish of the family Rajidae reaching a wingspan of about 1 metre. The diamond-shaped body, formed by the pectoral fins fused to the head, is brownish with light and dark spots giving good camouflage on the bottom. Characteristic are the rows of curved thorns on the back and tail and the large 'bucklers' on thickened skin plates, from which the species takes its name. It lives on sand and mud bottoms of the eastern Atlantic, the North Sea and the Mediterranean, from shallow water to hundreds of metres. On the bottom it hunts crabs, shrimps, shellfish and small fish. It lays eggs in horny capsules. Due to fishing it is assessed as Near Threatened (NT).
