Eurycea longicauda, commonly known as the long-tailed salamander or longtail salamander, is a species of lungless salamander native to the Appalachian Region and Ohio River valley of the eastern United States. It is a "cave salamander" that frequents twilight zones of caves and also inhabits springs and surrounding forest.
Eurycea guttolineata has earlier been treated as a subspecies of Eurycea longicauda (that is, as E. l. guttolineata), but is now considered a full species. The eggs measure 7 mm (0.28 in) in diameter. The larvae hatch in January–March at about 10 mm (0.39 in) snout–vent length (SVL)... Wikipedia →

Possible
About 20% of wildlife watchers report a Long-tailed Salamander sighting in Shenandoah National Park on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 20 amphibians we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Long-tailed Salamander in Shenandoah National Park on a given day, against about 10% in May and June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Long-tailed Salamander sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Long-tailed Salamander sightings, Shenandoah National Park has the highest daily chance: about 20%. Next come Great Smoky Mountains National Park (United States, about 20%).
Same genus: Eurycea
The closest relatives of the Long-tailed Salamander that you can see in Shenandoah National Park (genus Eurycea, Brook Salamanders) are Northern Two-lined Salamander (about 40%) and Southern Two-lined Salamander (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Long-tailed Salamander is recorded against all the amphibians logged in Shenandoah National Park (66 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.
