Reginaia rotulata

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Reginaia rotulata faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development throughout its limited range. Dam construction and water diversions have significantly altered the freshwater systems this mussel depends on for survival. Sedimentation from erosion and pollution from agricultural runoff further degrade the water quality essential for filter-feeding mollusks like this species.

Threat summary

Habitat

This freshwater mussel inhabits clean, flowing rivers and streams with sandy or gravelly substrates in the southeastern United States. It requires well-oxygenated water with stable flow regimes and depends on specific fish hosts for larval development.
