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 />
