Alabama heelsplitter

The phrase Alabama heelsplitter has been used as a common name for two different species of American river mussels, freshwater bivalves, both of which can be found in Alabama. The two species are:

• Lasmigona alabamensis = Lasmigona complanata alabamensis, still known as the "Alabama heelsplitter"

• Potamilus inflatus now known as the "Inflated heelsplitter"; this species was previously sometimes called "Alabama heelsplitter", and this caused confusion, hence the common name was changed
