description Red Salamander Overview

Pseudotriton ruber, the red salamander, is a stout-bodied lungless salamander (family Plethodontidae) native to the eastern United States. Adults are bright red or orange-red with scattered black spots, and their vivid coloration is thought to mimic the toxic red eft stage of the eastern newt (Notophthalmus viridescens). The species inhabits springs, seepages, and small streams in forested areas, where it feeds on insects, worms, and other small invertebrates. Four recognized subspecies occur across its range.

help Red Salamander FAQ

How can I distinguish a red salamander from a red eft?

A red salamander is usually stockier, smoother-skinned, and marked with numerous irregular black spots. A red eft is the terrestrial juvenile stage of the eastern newt, Notophthalmus viridescens, and typically has black-bordered red spots.

Why is Pseudotriton ruber called a lungless salamander?

It belongs to the family Plethodontidae, whose members lack lungs. Oxygen is exchanged through the skin and tissues lining the mouth, which helps explain the species' association with moist springs and stream margins.

Does the red salamander mimic a poisonous species?

Researchers have proposed that its bright coloration resembles the toxic red eft stage of the eastern newt. The relationship has been discussed as defensive mimicry because predators may learn to avoid similarly colored salamanders.

Where should I look for a red salamander in the wild?

The species occurs across much of the eastern United States, from parts of New York through the Appalachians and into the Southeast. It is commonly associated with cool springs, small streams, wet leaf litter, and cover objects near water.
