Big cave salamander discovery in Tennnessee, USA


This June 2017 video from the USA says about itself:

On this episode of Breaking Trail, Coyote and the crew hike deep into the West Virginia hills in search of the rare and cryptic Cave Salamander!

However, locating the cave is the only the first obstacle. Once the cave is found they must go spelunking deep into the mountain braving the darkness, cold and giant spiders until the beams of their flashlights illuminate one of these beautiful amphibians…or so they hope!

From the University of Tennessee at Knoxville in the USA:

Record-breaking salamander

January 25, 2019

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.

Salamanders are one of only two vertebrate animal groups to have successfully colonized caves. The other is fish, said Gladstone.

The record-breaking specimen had some damage to the tail, leading researchers to believe that it was once nearly 10 inches long.

The Berry Cave Salamander can be found in only 10 sites in eastern Tennessee, and in 2003 it was placed on the US Fish and Wildlife Service’s Candidate Species List for federal protection.

“This research will hopefully motivate additional conservation efforts for this rare and vulnerable species,” said Gladstone.
