Chunky False Brook Salamander

The Chunky False Brook Salamander (Aquiloeurycea cephalica) is a Least Concern plethodontid salamander endemic to Mexico, found in cloud forest and humid montane habitats in the Sierra Madre Oriental and related mountain ranges. The genus Aquiloeurycea is a recently erected Mexican endemic genus segregated from the broader genus Pseudoeurycea, comprising several small, robustly built (hence 'chunky') salamanders associated with high-elevation forests. Like all plethodontids, A. cephalica is a lungless salamander that breathes entirely through its moist, vascularized skin and the lining of its mouth. It is a direct developer, skipping the aquatic larval stage entirely and laying eggs in terrestrial microhabitats such as rotting logs, leaf litter, and soil. A. cephalica inhabits cool, humid forests of pine-oak and cloud forest zones in northern Mexico, where it forages for small invertebrates in the leaf litter and soil. The IUCN assesses it as Least Concern due to its reasonably wide distribution within its montane range. Deforestation, cattle grazing, and the conversion of cloud forest to agriculture represent ongoing threats to populations throughout its range.
