Desmognathus quadramaculatus, Blackbelly Salamander

This is one of the lighter ones I've caught, usually they are a little darker in North Carolina with a chestnut pattern over a dark dorsum, but this guy has a lighter coloration that blends in nicely with the lichens on the stone. It was about 14cm. 

Juvenile coloration and patterning, at 6cm.
