Comprehensive DescriptionRead full entry
This species of plethodon is sometimes described as a "worm with legs." In adults, the elongated body averages 40 mm SVL and is fit with short legs set far apart. The rounded tail is usually as long as the body, ranging from 65-143 mm. Adult P. electromorphus individuals are dark brown in coloration. Around the dorsal and venter regions, spots of color ranging from a very dark gold to greenish-gold to silver-white break up the otherwise uniform brown. Only the area around the throat is found to be a lighter color.
Newly hatched individuals are light gray above and black with patterns of white spots below. They range from 14-15 mm SVL (Regester 2000).
The species name, electromorphus, comes from the electrophoretic protein characteristics that differentiates this species from Plethodon richmondi (Regester 2000).
