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!

This page summarizes the current data on the richness and endemism of species in each biogeographical region and subregion, as well as by family.

These data update Table 4 of Graf & Cummings (2021).

Numbers within parentheses indicate the richness of endemic species in each subregion. Family abbreviations: UN, Unionidae; MA, Margaritiferidae; HY, Hyriidae; ET, Etheriidae; MY, Mycetopodidae; IR, Iridinidae.

For a more detailed summary of species and genus richness by taxonomy, see Updated Table 3: Richness of species and genera arranged by taxonomy and region.
