Potamonautes infravallatus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Potamonautes infravallatus faces significant pressure from water pollution and sedimentation in its freshwater habitats, particularly from agricultural runoff and urban development. The species is highly sensitive to water quality changes, making it vulnerable to chemical contamination from pesticides and industrial discharge. Habitat fragmentation through dam construction and water extraction further isolates populations and reduces genetic diversity.
Habitat
This freshwater crab inhabits rivers, streams, and associated riparian zones in southern Africa, typically preferring areas with rocky substrates and moderate water flow. The species requires clean, well-oxygenated water and is often found in mountainous or hilly regions where water quality remains relatively pristine.
