Maximum length 60 cm. The brown back, mottled with dark spots, bears two false ‘eyes’, as shown in the drawing. These, which are blue in the centre, are sometimes likened to mirrors. They have the merit of making this species quite unmistakable among the eighteen or so species of ray present in the Mediterranean. Few languages and few people attempt to distinguish between them.

The last two appear also in Malta as hamiema and rajja.
