Green salamander

The only salamander of the genus Aneides to live in the Eastern United States, green salamanders live predominantly in wet, damp crevices.

Physical Description

Green salamanders are mottled green and black, gray or brown with lighter bellies that are bluish grey to pale yellow. This mottled patterning provides the green salamander with camouflage from predators, especially when hiding among the mosses and lichen its skin resembles. Their flattened bodies, long limbs and square-shaped toes help them to easily climb and fit into rock and log crevices.


Adults may reach 3 to 5 inches (7.6 to 12.7 centimeters) in length, with females measuring slightly longer than males.

Native Habitat

Green salamanders are indigenous to the Appalachian region, with a patchy distribution from southern Pennsylvania to northern Alabama and Mississippi. Isolated populations occur west to Indiana and east to North and South Carolina.

They prefer rocky habitats, including sandstone and limestone outcroppings or caves and are most often found in tree or rock crevices. When not tucked into a crevice, green salamanders can be found among other moist or damp environments, including bark, leaves and logs.

Food/Eating Habits

In the wild, green salamanders feed on a wide variety of small invertebrates, including arachnids, insects, snails and slugs.

At the Smithsonian's National Zoo, green salamanders receive a mixture of crickets, fruit flies, bean beetles, isopods, springtails and black worms.

Reproduction and Development

Green salamander breeding season is from May to late September. Males breed annually, while females breed every other year. Females lay between 10 and 30 eggs in rock or log crevices and guard their eggs until they hatch 80 to 90 days later. Young stay with their mother for one or two months and will reach maturity around the age of three.

Sleep Habits

From approximately December to April, green salamanders are largely inactive. During the warmer months, they are primarily nocturnal in search of food.


Lifespan for the green salamander is unknown.

Green salamanders are threatened by development of roads, over-collecting, habitat loss, over-harvesting, disease and drought.

This species occurs in many protected areas and is regionally listed as endangered or threatened in many of the states where it occurs.
