Paedomorphic two-lined in Ohio

This Thursday we ventured off to Harker's run and found a paedomorphic southern two-lined salamander, Eurycea cirrigera.

In the picture you can make out the paedomorphic traits if you look close enough to it's neck.

Here's some general information about Eurycea cirrigera:
The distinct feature on these salamanders are the two-lines running down it's back and they extend to the tip of the tail, while the lines become more dashed on the northern two-lined salamander. Can have cirri, which some speculate is for the purpose of detecting female chemicals. They live close to water, both in woodland and open areas, and can be found under rocks. This one specifically was found in the water because it retains gills from it's larval stage. The population of this creature isn't in danger, but land alteration and pollution has a potential to drop the population of this species. (Post by Bahram Khosraviani)
