Summary:
Researchers have discovered the largest individual of any cave salamander in North America, a 9.3-inch specimen of Berry Cave salamander.



Researchers at UT have discovered the largest individual of any cave salamander in North America, a 9.3-inch specimen of Berry Cave salamander. The finding was published in Subterranean Biology.

"The record represents the largest individual within the genus Gyrinophilus, the largest body size of any cave-obligate salamander and the largest salamander within the Plethodontidae family in the United States," said Nicholas Gladstone, a graduate student in UT's Department of Earth and Planetary Sciences, who made the discovery.

The find is making scientists reexamine growth limits of these animals in harsh environments and how hospitable underground environments really are.

Salamanders can be found in a variety of habitats across Tennessee. Some species have adapted to live in cave environments, which are thought of as extreme and inhospitable ecosystems due to the absence of light and limited resources.
