The eastern newt (Notophthalmus viridescens) is a common newt of eastern North America. It frequents small lakes, ponds, vernal ponds and streams or nearby wooded areas. The eastern newt produces tetrodotoxin, which makes the species unpalatable to predatory fish and crayfish. It has a lifespan of 12 to 15 years in the wild, and it may grow to 5 in (13 cm) in length. These animals are common aquarium pets, being either collected from the wild or sold commercially. The striking bright orange juvenile stage, which is land-dwelling, is known as a red eft. Some sources blend the general name of the species and that of the red-spotted newt subspecies into the eastern red-spotted newt (although there is no "western" one).
The eastern newt includes these four subspecies: Red-spotted newt (Notophthalmus viridescens viridescens); Broken-striped newt (Notophthalmus viridescens dorsalis); Central newt (Notophthalmus viridescens louisianensis) - Central newts measure from 2.5 in (6.4 cm) to 4 in (10 cm) in length. They are brown or green, with fine black dots all over the body. There may be a row of red spots on each side of the body. The belly is yellow or orange and is noticeably... Wikipedia →

Possible
About 30% of wildlife watchers report an Eastern Newt sighting in Acadia National Park on a given day, based on 133 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report an Eastern Newt in Acadia National Park on a given day, against under 5% in November to February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Eastern Newt sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 6
Of the 6 parks where we can rate Eastern Newt sightings, Acadia National Park ranks 2nd at about 30%. The best odds are in Shenandoah National Park (United States, about 50%). All parks ranked.
Same order: Caudata
The closest relatives of the Eastern Newt that you can see in Acadia National Park (order Caudata, Salamanders) are Eastern Red-backed Salamander (about 40%), Spotted Salamander (about 40%) and Four-toed Salamander (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Newt is recorded against all the amphibians logged in Acadia National Park (133 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.
