Haha will do that. So complex, and yet people still put it down to chance

In Britain there are six species of Freshwater Mussel.
Five unionid species:
Anodonta anatina.
Anodonta cygnea.
Unio tumidus .
Pseudanodonta complanata.
And one margaritiferid species:
Margaritifera margaritifera.

Pseudanodonta complanata. The Depressed River Mussel, and Margaritifera margaritifera. The Pearl Mussel are now very scarce.

There is also the introduced Zebra Mussel - Dreissena polymorpha .
Dorts.

Hi Nige.

You may find these two sites of interest regarding British Marine Bivalves...

Index for Mytilacea species

and

An interesting question Nige as I thought it would be really easy to find a straightforward description of classification, but I was wrong.

Hope this (unfortunately American, so the spelling is a bit odd in places) animal classification helps.
