Potamonautes pilosus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Potamonautes pilosus faces significant pressure from water pollution and sedimentation in South African river systems, particularly from agricultural runoff and urban development. Habitat degradation through dam construction and water abstraction has fragmented populations and altered natural flow regimes essential for breeding. Mining activities in the species' range contribute heavy metals and other contaminants that directly impact water quality and crab survival.
Habitat
This freshwater crab inhabits rocky streams and rivers in the Eastern Cape and KwaZulu-Natal provinces of South Africa, typically found under stones and in crevices of fast-flowing, well-oxygenated waters. The species requires clean, unpolluted freshwater systems with stable substrates for shelter and breeding.
