Behavior and life underground

Spotted salamanders are mole salamanders that spend most of the year hidden in burrows and under logs in the forest, rarely seen above ground. They emerge in large numbers on the first warm, rainy nights of spring to migrate to breeding pools. Their bright yellow spots are thought to warn predators of distasteful skin secretions.

Diet and feeding

These salamanders are carnivores that eat earthworms, insects, spiders, slugs, snails, and other small invertebrates. They hunt slowly on the forest floor, seizing prey with a quick snap of the jaws. Larvae in the breeding pools are aquatic predators that eat tiny invertebrates.

Habitat and range

The spotted salamander ranges across the eastern United States and southeastern Canada in moist deciduous and mixed forests. It depends on fishless seasonal pools, known as vernal pools, for breeding, returning to the same pools year after year. A remarkable feature is that algae grow inside its developing eggs, supplying the embryos with oxygen.

Conservation

The species is listed as Least Concern and remains widespread, but it relies on both intact forest and the temporary pools where it breeds. Threats include the draining of vernal pools, forest clearing, road mortality during migrations, and pollution. Protecting clusters of breeding pools and the surrounding woodland is key to its survival.

Did you know? Spotted Salamander facts

• The spotted salamander is a stout, secretive mole salamander of eastern North America, instantly recognized by two rows of bright yellow spots on its dark body.
• The two rows of bright yellow spots are thought to be a warning to predators that the salamander's skin produces a distasteful, mildly toxic secretion.
• They are carnivores that eat earthworms, insects, spiders, slugs, and snails, hunting slowly across the moist forest floor at night.
• They live in moist deciduous forests across the eastern United States and southeastern Canada, spending most of the year underground and breeding in seasonal woodland pools.
• Spotted salamanders are long-lived and can survive 20 years or more in the wild, with some individuals living even longer.
• Conservation: Least Concern (IUCN).

Communication

• Spotted Salamander uses scent, posture, and vocal signals to mark territory and coordinate social behaviour.
• Communication intensity often peaks during breeding seasons and territorial disputes.

Habitat & range

Moist deciduous forest with vernal pools

Ecological role

Spotted Salamander acts as a predator that helps regulate prey populations and maintain balance in moist deciduous forest with vernal pools.
