In 1989, D. Bruce Means and Alvin A. Karlin described a new species
of salamander (Desmognathus apalachicolae), commonly known as
the Apalachicola dusky salamander. This species is found only in the
deep, moist ravines south of the Fall Line in the Ochlockonee, Apalachicola-Flint-Chattahoochee,
and upper Choctawhatchee river systems in Alabama, Georgia, and Florida.
Means and Karlin speculate that the Apalachicola dusky salamander may
have evolved from a population of salamanders isolated in the ravines
during climate changes following the Pleistocene.
