Brownback Salamander vs Apalachicola Dusky Salamander
The brownback salamander and Apalachicola dusky salamander are both small, lungless amphibians confined to narrow parts of the southeastern United States, each illustrating a different way southeastern salamander diversity has been quietly hiding in plain sight.

Brownback Salamander vs Apalachicola Dusky Salamander: common questions
How is the brownback salamander different from the Apalachicola dusky salamander?
The brownback salamander depends on spring-fed wetlands within a limited part of Alabama and Georgia and was only recently split from the broader dwarf salamander complex based on genetic study, while the Apalachicola dusky salamander is tied specifically to ravine and seepage habitat along the Apalachicola River system, a narrow range defined by one particular river drainage rather than a cryptic species split.
Why are both of these salamanders so hard to identify by appearance?
The brownback salamander looks extremely similar to its close dwarf salamander relatives, a similarity that kept it hidden as a distinct species until genetic study revealed the difference, while the Apalachicola dusky salamander overlaps in appearance with several other dusky salamander species sharing parts of the same general region, making range often more useful than looks for identifying either species confidently.
Do both of these salamanders breathe through their skin?
Yes, both species are lungless, breathing entirely through their moist skin and the lining of the mouth, an adaptation shared broadly across their families that ties both species closely to the consistently damp spring-fed or seepage habitat each one specifically depends on.
