Updated Table 3: Richness of species and genera arranged by taxonomy and region

This page summarizes the current data on the richness of freshwater mussel taxa worldwide, as well as in each biogeographical region.

The table below updates 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.
