Chugoku-buchi-sanshou-uwo

The Chugoku Blotched Salamander (Hynobius sematonotos) is a Vulnerable salamander endemic to the Chugoku region of western Honshu, Japan. It belongs to the family Hynobiidae, the most basal family of living salamanders, with the greatest diversity concentrated in East Asia. Like other Hynobius species, H. sematonotos reproduces externally: females deposit paired egg sacs in small streams or water bodies, where males fertilize them externally before larvae hatch and develop in the water. Adults are terrestrial outside the breeding season, living under logs and leaf litter in cool forest habitats. The Chugoku Blotched Salamander is named for the distinctive blotched or marbled pattern of its dorsal coloration. Its Vulnerable status reflects ongoing habitat loss from deforestation, urbanization, and stream modification in the Chugoku region, which has experienced substantial land-use change. The species' dependence on small headwater streams for breeding makes it particularly sensitive to water quality degradation and hydrological alteration. Like many Japanese hynobiids, it faces additional threats from invasive species and pollution. Conservation of forested headwater catchments is essential for maintaining viable populations of this and related endemic Japanese salamanders.
