Cuckoo rays are a relatively small sized ray belonging to the skate family and are often marketed simply as skate wings. They are identified by 2 large, dark, false eyespots their sandy coloured back. They having a rough upper skin with large skin teeth along the tail. The cuckoo ray is one of 5 similar Rajid skate species found in our waters. Identification of rays is not easy so ray landing records are not usually accurately broken down to species level.
Skates and rays are slow growing, late maturing and lay a small number of eggs per year so are highly vulnerable to fishing pressure. This species is not actively targeted but significant quantities are caught as bycatch in trawl and net fisheries.
