The three-lined salamander (Eurycea guttolineata) is a species of salamander in the family Plethodontidae. It is endemic to the south-eastern United States. This species was classified as a sub-species of long tailed salamanders until DNA sequencing revealed that there was no hybridization between the two species. Like other Plethodontidae species, E. guttolineata captures prey via tongue projection.
Eurycea guttolineata is a mid-sized, slender stream salamander which ranges from about 10-15.9 cm in its adult form. It is tan to light yellow with three black longitudinal stripes running from the eyes down the length of the body to the tail. They possess 13-14 costal grooves that aid in cutaneous respiration. The tail is very long at approximately two-thirds its total body length. Additionally, the ventrum (belly) of the three-lined salamander is boldly marked with black and white marbling.
Breeding takes place in slow moving bogs and streams. Hatchlings are generally around 10-13 mm and undergo metamorphosis when they are 22-27 mm snout-to-vent length. Metamorphosis starts with the reduction of labial folds, formation of eyelids, and resorption of... Wikipedia →

Possible
About 30% of wildlife watchers report a Three-lined Salamander sighting in Congaree National Park on a given day, based on 56 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 3rd most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
April to August
In those months about 40% of wildlife watchers report a Three-lined Salamander in Congaree National Park on a given day, against under 5% in December and January, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Three-lined Salamander sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 2 parks where we can rate Three-lined Salamander sightings, Congaree National Park has the highest daily chance: about 30%. Next come Great Smoky Mountains National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Three-lined Salamander is recorded against all the amphibians logged in Congaree National Park (56 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
