Caddo Mountain Salamander

The Caddo Mountain salamander (Plethodon caddoensis) is exclusively endemic to the rocky ravines and slopes of the Caddo Mountains in Arkansas. It has an exceptionally restricted geographic range, found only within this specific isolated mountain region. The salamander relies heavily on the cool, moist microclimates provided by the rocky crevices.

This amphibian belongs to the Plethodontidae family, meaning it is entirely lungless. It absorbs oxygen directly from the air through its moist skin and the lining of its mouth. Because of this, it must live in damp, humid environments to prevent its skin from drying out and to facilitate respiration.

Like most terrestrial salamanders, the Caddo Mountain salamander feeds primarily on small, ground-dwelling invertebrates. Its diet consists of insects, mites, spiders, and various worms found in the leaf litter of the forest floor. It uses a quick, projectile tongue to capture its prey.

Because it is restricted to such a small geographic area, the Caddo Mountain salamander is highly vulnerable to habitat destruction. It is not currently listed as federally endangered, but it is monitored closely by state conservation agencies in Arkansas. Threats like logging, wildfires, and climate change pose significant risks to its limited populations.
