I was reading on Wikipedia (
http://en.wikipedia.org/wiki/Freshwater_pearl_mussel ) that the freshwater mussel is an endagered specie, this made me a little worried. Since they call the mussel Pinctada margaritifera I´m wondering if this information I got is correct though...
If it is, then maybe it´s just in countries such as Sweden (Where they are rare.) they are endagered?
