Lead-backed Salamander - Plethodon cinereus
I think this individual may have lost its tail and was in the process of regrowing it.
Plethodon cinereus exhibits color polymorphism with two common color variations - the 'red-backed' variety has a red dorsal stripe that tapers towards the tail and the 'lead-backed' variety lacks most or all of the red pigmentation. This spotting shows the lead-backed variety.
Habitat: Near the edge of a pond in a deciduous forest

The red-backed salamander is a species of small, hardy woodland salamander in the family Plethodontidae. The species inhabits wooded slopes in eastern North America, west to Missouri, south to North Carolina, and north from southern Quebec and the Maritime provinces in Canada to Minnesota.
