FRESHWATER MUSSEL (UNIONOIDA) GENERA OF THE WORLD
http://www.inhs.uiuc.edu/~ksc/MusselGenera.html
The objective of this page is to illustrate (with photographs) all of the "genera" of freshwater mussels (Unionoida) in the world. The genera included are largely those recognized by Haas (1969) with the exception of the North American fauna, which follow Turgeon, et al. (1998). Other deviations from Haas (1969) will be referenced to the new source of information. If anyone spots any errors or misspellings of type localities, type designations, rivers or other geographic names, please let me know and I will make appropriate changes. I plan on adding information on type species for each genus and a list of currently recognized species/taxa in the near future. An example of the kind of added information can be seen in the account for the genus Castalina. If anyone has any comments on how and what type of data to include in these species list sections, please let me know. I am still playing around with the format. Also understand that these pages (like many on the web) are "works in progress" and the data contained in them should be checked to the primary literature to ensure accuracy. Museum Acronyms used in photo captions follow: Systematic Research Collections - Mollusca.

These pages are by the same folks as above. Isn't it nice to know there are people who love the humble unios so much they dedicate their entire scientific life to them.

<H3>Making the World a Better Place, One Mollusk at a Time.

The MUSSEL Project (MUSSELp, for short) is an on-going study aimed at the global revision of the classification of the Unionoida, otherwise known as freshwater mussels. The two principle investigators of this work are Daniel L. Graf (DLG) and Kevin S. Cummings (KSC).
Toward this end, we are compiling an exhaustive database of all Recent unionoid species and genera described to-date. This database will eventually serve as the basis for a universal synthesis and revision of freshwater mussel taxonomy. Furthermore, we apply cladistic methods to test our hypotheses of evolutionary relationships. This allows us to use macroevolutionary pattern to test hypotheses of macroevolutionary process
