An extensive morphological and molecular study has examined over 200 specimens of European Polycera nudibranchs. Four species were distinguished, one of which proved to be new to science: Polycera kernowensis. Among other places – particularly in Cornwall (UK) – this new species was also discovered on the Dutch part of Dogger Bank.
