The spotted ray is a small, diamond shaped, spotted ray. The upper body is yellow to pale with a number of scattered dark spots, which do not reach the margin edge of the pectoral fins. The pectoral fins form almost right angles. The main body disc is undulated in both males and females but more pronounced in males. The maximum length is 80 cm but the average is 60 cm. The body disc is free from spines except for a central row of 20-50 thorns from midline to the first dorsal fins. Juveniles have small spines along the top edge of the body disk, which extend past the eyes. Juveniles have also been shown to have rows of spines along the side of their tail.
Recorded all around the coastline of the British Isles. It is one of the three most frequent skate species in the English Channel.
Recorded around the British Isles, the English Channel and west coast of France. Few records along the northern coast of Africa in Morocco and Tunisia. Also recorded in the Mediterranean and the west coast of South Africa.
The spotted ray has the most varied diet, compared to other North-East Atlantic ray species, composed of crustaceans, polychaetes, teleosts and molluscs. Catch rates are greatest in inshore beam trammel nets. Juveniles are mainly caught in these catches. Raja montagui can be grouped together with Raja clavata in catch data. The abundance of both species has been increasing since 2000 in the North Sea. Unlike Raja brachyura, the dark spots on the upper body do not extend to the marginal edge of the pectoral fins, which is a distinguishing feature. It has been recorded as ‘least concern’ on the IUCN red list.
