Eastern Newt
Notophthalmus viridescens
Quick answer
The eastern newt is a small North American amphibian with an unusual three-stage life cycle, including a brilliant orange land-dwelling juvenile called the red eft. Adults are olive-green and aquatic, and their skin contains a mild toxin for defense. Eastern newts can live up to 15 years.

Where it lives
Ponds, lakes, and moist woodlands across eastern North America, from Canada to the southeastern United States.
Behavior and life cycle
Eastern newts have a striking three-stage life. After hatching as aquatic larvae, many transform into bright orange juveniles called red efts that live on land for several years. The efts then return to water and mature into olive-green, semi-aquatic adults. The vivid orange of the eft stage warns predators of toxins in the skin.
Diet and feeding
Eastern newts are carnivores at every stage. They eat insects, worms, small crustaceans, snails, and amphibian eggs, including those of frogs. Adults forage in the water while red efts hunt small invertebrates on the moist forest floor.
Habitat and range
The eastern newt is widespread across eastern North America, from Canada to the southeastern United States. Adults live in ponds, lakes, and slow streams, while red efts roam the surrounding damp woodlands. The species needs both healthy wetlands and intact forest to complete its life cycle.
Conservation
Eastern newts are listed as Least Concern and remain common across much of their range. Their main threats are wetland loss, forest clearing, road mortality during migrations, and pollution. Protecting both breeding ponds and the surrounding forest is important because the species depends on both.
Frequently asked questions about the Eastern Newt
What is a red eft?
A red eft is the bright orange, land-dwelling juvenile stage of the eastern newt. After living on land for a few years, the eft returns to water and matures into an olive-green adult.
Are eastern newts poisonous?
Yes, mildly. Eastern newts have toxins in their skin that deter predators. The bright orange color of the red eft stage is a warning, but they are not dangerous to handle briefly, though you should wash your hands afterward.
What do eastern newts eat?
Eastern newts are carnivores that eat insects, worms, small crustaceans, snails, and amphibian eggs at all stages of their life.
How long do eastern newts live?
Eastern newts are long-lived for their size and can live up to about 15 years in the wild.
Where do eastern newts live?
They live across eastern North America. Adults inhabit ponds, lakes, and slow streams, while the juvenile red efts live in the surrounding moist woodlands.
