The four-toed salamander (Hemidactylium scutatum) is a lungless salamander native to eastern North America. It is the only species of the monotypic genus Hemidactylium. The four-toed salamander can be recognized by its white underbelly sprinkled with black dots. Its back varies from orange-brownish to red-brownish; its flanks are grayish. The body and the limbs are elongated. The snout is short, and the eyes are prominent. The tail color is usually brighter than the back, and you can observe a constriction at the body/tail junction. The posterior limbs have four toes (hence its name), a good identification criterion but hard to use in the field. This species rarely exceeds 10 cm (3.9 in) in length. In the breeding season (late October to early December) males have enlarged premaxillary teeth and truncated squarish snouts, which are round in females. The juveniles show a tail shorter than the body.
The four-toed salamander can be easily mistaken for the redback salamander (Plethodon cinereus) in the wild. The redback salamander's underbelly has more numerous black markings. Unlike the four-toed salamander, the redback salamander has no constriction at the tail base... Wikipedia →

Rare
Under 5% of wildlife watchers report a Four-toed Salamander sighting in Great Smoky Mountains National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 36th most-seen of the 36 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February and March
In those months about 10% of wildlife watchers report a Four-toed Salamander in Great Smoky Mountains National Park on a given day, against under 5% in April to January, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Four-toed 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.
2nd of 2
Of the 2 parks where we can rate Four-toed Salamander sightings, Great Smoky Mountains National Park ranks 2nd at under 5%. The best odds are in Acadia National Park (United States, about 10%).

GBIF citizen-science records
It is estimated from how often the Four-toed Salamander is recorded against all the amphibians logged in Great Smoky Mountains National Park (7 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.
