Hello Conchlers,

I received this letter from a gentleman in France and was wondering if
anyone can help!

In your writting on "class bivalvia"
 http://manandmollusc.net/advanced_introduction/moll101pelecypoda.html )you
wrote that bivalvia, pelecypoda and lamellibranchia  are the same.
But I've heard that bivalvia is a paraphyletic ( I don't know if it's the
same in english) group which contains lamellibranchias, brachiopodes and
ostracodes.
Can you explain me the difference

Thanks a lot
