Common Splayfoot Salamander

<em>Chiropterotriton chiropterus</em>, commonly known as the common splayfoot salamander, is a small lungless salamander in the family Plethodontidae, endemic to the Sierra Madre Oriental of Mexico. This species typically inhabits montane cloud forests and humid oak-pine forests at elevations ranging from approximately 1,200 to 2,500 metres, where it lives under rocks, logs, and within the leaf litter and moss of cool, moist forest floor microhabitats. Its geographic range is restricted to the states of Tamaulipas, Nuevo León, and adjacent parts of San Luis Potosí in northeastern Mexico. Classified as Critically Endangered on the IUCN Red List, <em>Chiropterotriton chiropterus</em> faces severe threats from deforestation, agricultural expansion, human settlement, and climate change, all of which are degrading and fragmenting the highly limited cloud forest habitats on which it depends. As a plethodontid salamander, it breathes entirely through its moist skin and buccal cavity. The species is carnivorous, typically feeding on small invertebrates such as insects, worms, and other arthropods found in the soil and leaf litter. Biological traits such as average lifespan, body length, and body weight remain poorly documented in the scientific literature for this rarely studied species.
