Apalachicola Dusky Salamander
Desmognathus apalachicolae · also called Apalachicola dusky salamanders
Within a shaded ravine seepage along the Apalachicola River system, an Apalachicola dusky salamander forages through damp leaf litter, its entire known range tied closely to the health of this one specific river drainage.
Overview
The Apalachicola dusky salamander, Desmognathus apalachicolae, is a small, lungless amphibian native to ravine and seepage habitat along the Apalachicola River system across parts of Florida, Georgia, and Alabama. Its comparatively narrow range, close dependence on shaded ravine seepages, and visual similarity to several other dusky salamander relatives make it a representative example of how tightly some southeastern salamander species are tied to a single river system.
A salamander named for its home river
The Apalachicola dusky salamander’s entire distribution traces back to one river system, a naturally narrow range that keeps its survival closely linked to the ongoing health of the Apalachicola’s ravines and seepages.
Status
Least Concern, present across suitable ravine and seepage habitat within its naturally restricted range along the Apalachicola River system.
Apalachicola Dusky Salamander: common questions
Where is the Apalachicola dusky salamander found?
This species is restricted to a comparatively narrow range tied closely to the Apalachicola River system and its associated ravines and tributaries across parts of Florida, Georgia, and Alabama, a naturally limited distribution compared with several more widely ranging dusky salamander relatives.
Why does the Apalachicola dusky salamander need ravine seepages specifically?
This species relies on the consistent moisture that shaded ravine seepages and stream banks provide, a habitat requirement tied directly to its complete lack of lungs, since it must keep its skin damp enough at all times to absorb sufficient oxygen through it to survive.
How can you tell an Apalachicola dusky salamander from other dusky salamanders?
This species displays a dark body with variable, subtle mottling that overlaps closely with several other dusky salamander relatives sharing parts of the same general region, so its comparatively narrow range along the Apalachicola River system is often more useful for confirming identification than appearance alone.
How big does an Apalachicola dusky salamander get?
This species is a relatively small, slender member of its genus, noticeably more modest in size compared with several larger dusky salamander relatives found across other parts of the southeastern United States.
