The public should be informed about Patella ferruginea as it is the most endangered marine mollusc in the Western Mediterranean. This species has been around since the Pleistocene and their populations have been in such decline it is only found in a few locations around the Mediterranean such us Gibraltar, Tuscany , Sardinia (Italy), Ceuta (Spain). The more the public is informed about this species I believe the more able will the public be to recognize it and not disturb it not only to help it survive but also because its illegal. In Gibraltar you can get fined up to £10000 for killing/disturbing even a single individual.
