Description

The Madeira skate is a skate of the family Rajidae reaching a total length of about 85 cm and endemic around the Macaronesian islands. The diamond-shaped body, formed by the pectoral fins fused to the head, bears thorns on the back and tail; the upper side is brownish and darkly mottled, the underside paler. The species closely resembles the thornback ray, and genetic research has long doubted whether it is really a separate species. It lives on sand and gravel bottoms of the continental shelf and slope around Madeira, the Azores and the Canaries. On the bottom it hunts crustaceans, molluscs and small fish. It lays eggs in horny capsules and grows slowly; because of its limited range it is assessed as Vulnerable (VU).
