Somanniathelphusa taiwanensis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Somanniathelphusa taiwanensis faces severe pressure from habitat degradation in Taiwan's freshwater systems, where agricultural runoff and urban development have compromised water quality in its native streams. Dam construction and water extraction for human use have altered natural flow regimes, fragmenting populations and reducing suitable breeding habitat. The species' limited distribution makes it particularly vulnerable to localized environmental changes and pollution events.
Habitat
This freshwater crab inhabits clean, well-oxygenated streams and rivers in Taiwan's mountainous regions, typically found under rocks and in crevices along rocky substrates. The species requires pristine water conditions and is sensitive to pollution and sedimentation.
