The Freshwater Mussels (Unionoida) of the World (and other less consequential bivalves)

FM(U)otW(aolcb) is the web version of the MUSSEL Project Database. Follow the links to browse the data or use the custom Google search field. Either way, you win!

The nominal species (available and otherwise) in this synonymy are listed by usage rather than strictly by publication date. The primary sorting order is by the most recent year (since 1969) that the species name was treated as valid, and then nominal species are sorted secondarily by publication year.

The taxonomic history of the valid species (since 1900) is listed at the bottom of the page.
