Freshwater Mussel Gallery
More than 290 species of unionids (freshwater mussels) are native to North America. However, the majority of unionids are imperiled, and in some regions,
individual species are at risk of extinction. This gallery of images and life history information is provided to help you explore the role they play in freshwater ecosystems, and their biology. Our goals are to peak your interest, encourage you to learn more and engage you in the collective effort to preserve these small, but wonderous creatures.
