Del Norte Salamander
Plethodon elongatus · also called Del Norte salamanders
A Del Norte salamander slips its unusually long, slender body into a gap between rocks on a talus slope, exactly the kind of tight, damp space its elongated shape is built for. Its narrow range along the California-Oregon border depends entirely on old-growth forest conditions that logging can quietly erode piece by piece.
Overview
The Del Norte salamander, Plethodon elongatus, is a lungless salamander native to coastal mountain forest and talus habitat near the California-Oregon border. Its elongated body is well suited to moving through narrow rocky crevices and forest debris.
A body shaped by tight spaces
Where many salamanders manage with a more standard build, the Del Norte salamander’s genuinely elongated form reflects a lifestyle spent squeezing through talus gaps and beneath logs, a body plan shaped directly by the habitat it depends on.
Status
Near Threatened — under pressure from logging that reduces the old-growth forest canopy and woody debris the species relies on.
Del Norte Salamander: common questions
Why does the Del Norte salamander have such an elongated body?
A Del Norte salamander's notably elongated, slender body is well suited to moving through the narrow spaces found within rocky talus slopes and beneath forest debris, an adaptation that reflects the species' close dependency on squeezing into tight rocky crevices and gaps between fallen logs.
Why is old-growth forest so important for the Del Norte salamander?
A Del Norte salamander depends on the shaded, consistently moist conditions and abundant fallen logs and deep leaf litter associated with mature, old-growth forest, so logging practices that remove canopy cover or clear woody debris can significantly degrade the specific habitat conditions the species requires to survive.
How does the Del Norte salamander defend itself from predators?
Like several other lungless salamanders, a Del Norte salamander can produce a sticky, distasteful skin secretion when threatened, a defensive adaptation that can deter a predator or make the salamander considerably more difficult to handle or swallow successfully.
Where is the Del Norte salamander found?
The Del Norte salamander is native to a relatively narrow range of coastal mountain forest and talus habitat near the California-Oregon border, a limited distribution that makes the species particularly sensitive to habitat changes occurring within that specific geographic area.
