The spotted ray (RAJA MONTAGUI)

has a flattened, diamond-shaped body with broad wing-like pectoral fins and a long tail. There are small spines on the front edge of the disc in young fish, in adults these spines extend to behind the eyes. The posterior part of the disc is free of spines, apart from one central row of large spines which runs from the centre of the disc, along the tail to the first dorsal fin. Young fish also have rows of spines along the sides of the tail. The upper surface of the ray is usually yellow to pale brown with numerous dark brown-black spots which do not extend to the edges of the disc. Often there is an ocellus (eye-spot) on each wing. Adult fish can grow to 75cm in length .

This species is widespread all around the coasts of Britain and Ireland but appears to be absent from the east coast of England. The spotted ray is similar in size and shape to the thornback ray (Raja clavata) however the latter has characteristic large spines with button-like bases scattered over its back.
