Is there any help for pearl mussels?
We hear and read so much about plants and animal species being threatened by extinction, but not all species make headlines, like for instance the freshwater pearl mussel with the beautiful name Margaritifera margaritifera. Not only oysters and other marine molluscs produce pearls: the freshwater pearl mussel of the holarctic region on both sides of the Atlantic has for centuries yielded valuable wild pearls, too. But the times when these bog mussels were literally plastering the beds of fast flowing streams of areas poor in nutrients and calcium are nearly over – and that despite the fact that this animal can probably reach an age of 200 or even more years. —>—>
