Description

The cuckoo ray is a flat cartilaginous fish of the family Rajidae reaching a wingspan of about 80 cm. The diamond-shaped body, formed by the pectoral fins fused to the head, is brownish, but its unmistakable feature is a large eyespot on each pectoral fin: a black-and-yellow marbled circle. The species lives on sand and mud bottoms of the continental shelf of the north-eastern Atlantic, the North Sea and the Mediterranean, from shallow water to nearly a thousand metres. On the bottom it hunts crabs, shrimps, worms and small fish. It lays eggs in horny capsules. Its stock is considered fairly stable, so the species is assessed as Least Concern (LC).
