Spotted Salamander<br />

Distribution: Eastern U.S. except the southeast coastal<br />

plain, north to southern Ontario, Quebec, and Canada.<br />

<strong>Maine</strong> <strong>Focus</strong> Region: Statewide<br />

Home Range/Movement: Most spend adult life within<br />

1,000 feet of breeding pools<br />

Food: Feeds on earthworms, insects, spiders, and slugs and<br />

other invertebrates found in rotting wood and subterranean<br />

tunnels<br />

Special Habitat Needs: Breeds in seasonal or semipermanent,<br />

fishless pools (vernal pools)<br />

Management:<br />

In April or May survey for vernal pools, which usually can be identified by the presence of egg masses.<br />

Manage forest cover and protect soils around vernal pools as described in the vernal pools management<br />

guide (Section 5).<br />

Comments: 6-8 in. long and dark brown to blue-black with bright yellow spots, the spotted salamander is easily<br />

identified. It is most often seen as it migrates to vernal pools during the spring breeding season from mid March to<br />

late April on warm, rainy nights. Oval, generally fist-sized or smaller masses of up to 200 eggs surrounded by a<br />

thick gelatinous envelope are attached to fallen branches. Egg masses may be milky white or clear, but often turn<br />

greenish with algae. Eggs hatch in 1-2 months. Transformation from aquatic larvae to terrestrial juveniles with<br />

lungs takes place 2.5-3 months later. Adults spend most of their life in the forest floor but often emerge on moist<br />

nights to search for prey. Habitat loss from development near pools is the greatest threat to spotted salamanders. Its<br />

close relative the blue-spotted salamander has similar habits.<br />
