Lasmigona alabamensis
Lasmigona alabamensis, common name Alabama heelsplitter, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae. Confusingly, a different species, Potamilus inflatus, has also sometimes been listed as "Alabama heelsplitter". In order to avoid confusion, that species has now been given the common name "inflated heelsplitter". References
