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 of species and genera worldwide, as well as in each biogeographical region.

These data update Table 3 of Graf & Cummings (2021).

Numbers in parentheses indicate the richness of genera. Region abbreviations: NA, North America; CA, Central America; SA, South America; AF, Afrotropics; EU, North Eurasia; AS, East Asia; AU, Australasia.

For a more detailed summary of species richness and endemism by geography, see Updated Table 4: Species richness and subregional endemism by geography and family.
