Negros Spotted Water Snake

Tropidonophis negrosensis

Unknown

Overview

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

The Negros Spotted Water Snake faces severe habitat degradation across its limited range on Negros Island in the Philippines. Agricultural expansion, particularly sugarcane cultivation, has fragmented and destroyed much of the freshwater wetland habitats essential for this semi-aquatic species. Urban development and water pollution from agricultural runoff further compromise the quality of remaining aquatic ecosystems where this endemic snake depends for feeding and reproduction.
