Glyptothorax kudremukhensis

Glyptothorax kudremukhensis is a critically endangered freshwater catfish endemic to the Western Ghats of Karnataka, India. This small bottom-dwelling fish belongs to the family Sisoridae and is characterized by its flattened body and adhesive ventral surface that allows it to cling to rocks in fast-flowing streams. The species was first described from the Kudremukh region, from which it derives its name. It inhabits clear, oxygen-rich mountain streams with rocky substrates at moderate to high elevations within the biodiversity hotspot of the Western Ghats. The fish's extremely limited distribution makes it particularly vulnerable to environmental changes and human activities. Primary threats include habitat degradation from mining activities, deforestation, agricultural runoff, and water pollution. The Kudremukh region has experienced significant ecological pressure from iron ore mining operations, which have altered stream flow patterns and water quality. Additionally, land use changes in the catchment areas have increased sedimentation and reduced water clarity in the streams where this species occurs. Climate change poses an additional threat through potential alterations to rainfall patterns and stream temperatures. Conservation efforts have been limited, though the establishment of Kudremukh National Park has provided some habitat protection. The species' conservation status highlights the urgent need for targeted research to better understand its ecology, population status, and specific habitat requirements. Effective conservation will require strict protection of remaining pristine stream habitats and restoration of degraded areas within its range.
