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!
For each taxon, information is provided regarding habitat, horizon (Recent unless otherwise listed), and diversity. We are actively working on the Recent freshwater mussels, and those are the taxa for which the data are most complete. For other Recent freshwater bivalves, the information largely follows Graf (2013). For other taxa (e.g., marine, fossil), any content is largely incidental.

Bivalvia | Unionoida | Unionoidea family UNIONIDAE Rafinesque, 1820
68 nominal families as synonyms | cladomics
Global Distribution of the Unionidae. The blue majority of the pie depicts the relative Recent species diversity of the family in the order Unionoida (816 of 1020).
The Unionidae is the richest of the six extant freshwater mussel families by far. We currently recognize 816 Recent species (175 genera) worldwide, and there are representatives in each of the six geographical regions. In the no-so-distant past, we punted with regard to the infra-familial arrangement of the Unionidae. The classification has since been updated and is applied here. We currently recognize 6 Recent subfamilies.
