Ocmulgee Slimy Salamander
Plethodon ocmulgee · also called Ocmulgee slimy salamanders
Beneath a log in a central Georgia forest along the Ocmulgee River drainage, an Ocmulgee slimy salamander sits nearly indistinguishable from a dozen other species that once shared its name, until genetic study revealed this river drainage’s population as its own genuinely distinct species.
Overview
The Ocmulgee slimy salamander, Plethodon ocmulgee, is a lungless amphibian native to forested habitat within the Ocmulgee River drainage of central Georgia. Its recent split from the broader slimy salamander species complex, sticky defensive skin secretion, and glossy black body flecked with white make it a representative example of just how much hidden species diversity modern genetic study has revealed within a single old, familiar name.
One species that turned out to be many
What field biologists spent decades treating as a single widespread slimy salamander turned out, under genetic scrutiny, to be a whole collection of separate species, with the Ocmulgee slimy salamander representing the specific river-drainage piece of that puzzle in central Georgia.
Status
Least Concern — widespread and stable across suitable forested habitat throughout the Ocmulgee River drainage of central Georgia.
Ocmulgee Slimy Salamander: common questions
Why was the Ocmulgee slimy salamander only recently recognised as its own species?
This species was formally split off from a much broader, historically defined slimy salamander complex following genetic studies that revealed the group actually contained more than a dozen distinct species across the southeastern United States, each looking extremely similar to the others despite being genetically separate.
How can you identify an Ocmulgee slimy salamander?
Look for scattered white or brassy flecks across an otherwise glossy black body, a pattern shared broadly across the wider slimy salamander group, meaning that confirming this specific species depends heavily on knowing it was found within the Ocmulgee River drainage rather than on any unique visual feature.
Why is it called the slimy salamander?
This species produces a notably sticky skin secretion when handled or threatened, a defence shared with other members of the slimy salamander group that can be genuinely difficult to wash off the hands and is thought to deter many potential predators from attempting a repeat attack.
How is the Ocmulgee slimy salamander different from its close relatives?
The differences between this species and other recently split members of the slimy salamander complex, such as the South Carolina or Chattahoochee slimy salamanders, come down almost entirely to geographic river-drainage range and subtle genetic distinctions rather than obvious visual features, since all share a broadly similar glossy black, white-flecked body plan.
