Cloud Forest Salamander from Cofre de Perote

The cloud forest salamander from Cofre de Perote is a lungless salamander in the genus Chiropterotriton (family Plethodontidae) endemic to the cloud forests and humid pine-oak woodlands of the Cofre de Perote volcanic massif in Veracruz State, Mexico. Chiropterotriton species are small, fully terrestrial plethodontid salamanders that lay terrestrial eggs and have direct development without an aquatic larval stage, a key adaptation to life at high elevations. They inhabit moist leaf litter, rotting logs, and moss mats in cloud forest at elevations between 2,000 and 3,500 meters, feeding on small invertebrates. The Cofre de Perote massif supports several endemic and near-endemic amphibian species due to its isolation as a distinct highland island surrounded by lowland habitats. This salamander faces severe threats from deforestation and degradation of cloud forest on the Cofre de Perote through clearing for agriculture and livestock grazing, drought stress from altered cloud immersion patterns associated with climate change, and the extremely limited extent of remaining suitable habitat on this single volcanic peak.
