Cofre de Perote Salamander

The Cofre de Perote Salamander (Isthmura naucampatepetl) is a critically endangered lungless salamander in the family Plethodontidae, known only from a single extinct volcanic peak—Cofre de Perote (Nauhcampatépetl) in the Mexican state of Veracruz. As a plethodontid, it relies entirely on cutaneous respiration through its moist skin, making it acutely dependent on cool, humid montane cloud forest conditions at high elevations. The species is associated with the pine-oak and cloud forest zones near the summit of Cofre de Perote, an isolated habitat island rising above the surrounding lowlands of Veracruz state. Such extreme topographic restriction means the entire species occupies an area of a few square kilometres, making it one of the most geographically limited vertebrates in North America. It is classified as Critically Endangered by the IUCN due to its extremely small and severely fragmented range, ongoing habitat degradation from agricultural encroachment, logging, and reforestation with non-native pine species, and the probable future impacts of climate change on cloud forest at high elevation. Population size estimates are very uncertain, but field surveys have found the species to be extremely rare. No captive breeding programmes are currently known to exist for this taxon.
