註釋The species Margaritifera margaritifera still lives in the rivers of many European states, where its presence is always linked to excellent water quality. Margaritifera auricularia was thought to be extinct during many years, but populations were discovered in the Ebro river (Spain) and in the Loire basin (France) , where they are critically endangered. Action Plans are presented for both species.
