Longsolid (Fusconaia subrotunda)

The Longsolid has a large distribution throughout the Eastern United States but is imperiled among much of its distribution, earning the listing of federally threatened. The Longsolid can grow up to 125 mm in length, and individuals found in larger rivers tend to have a thicker and more inflated shell than those found in smaller rivers, making this an adaptable species. In headwater streams, this mussel occurs in shoal habitats, but it can also be found in the tailraces of dams with depths of up to 6 feet. The Longsolid prefers gravel substrates or a mix of gravel and sand substrates free of silt.
