Pleurocera curta

Unknown

Overview

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

Pleurocera curta faces significant pressure from water quality degradation and sedimentation in its freshwater habitats throughout the southeastern United States. Dam construction and channelization have altered natural flow regimes that this species depends on for reproduction and feeding. Agricultural runoff and urban development have increased nutrient pollution and siltation, which can smother the rocky substrates where these snails graze on algae and detritus.
