Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Inflated Heelsplitter faces severe population declines primarily due to dam construction and river channelization that fragment populations and alter flow regimes essential for reproduction. Water pollution from agricultural runoff and urban development degrades water quality, while sedimentation from land-use changes smothers mussel beds. The species' dependence on specific fish hosts for larval development makes it particularly vulnerable to declining fish populations in modified river systems.
Habitat
Potamilus inflatus inhabits medium to large rivers with stable substrates of sand, gravel, and mud in areas with moderate to swift currents. The species typically occurs in depths of 1-6 meters in main channel habitats and requires clean, well-oxygenated water for survival and reproduction.
