Fin's Fish Guide
The Rough ray (Raja radula) is a saltwater fish of the family Rajidae that grows up to 70 cm.
Description
The rough ray is a diamond-shaped ray of the family Rajidae (true skates) reaching a disc width of about 70 cm. The upper side is brown with fine mottling and feels rough like a rasp due to its densely set granular skin denticles - hence the name 'radula'. Rows of thorns run over the back and tail, but unlike stingrays it lacks a venomous spine. The species is endemic to the Mediterranean and lives on sand and mud bottoms of the continental shelf. On the bottom it hunts crabs, shrimps, crustaceans and small fish. It is egg-laying. Through fishing pressure and bycatch it has declined and is assessed as Endangered (EN).
