Behaviour

Slimy salamanders have no lungs and breathe through their moist skin. When grabbed they release a thick, sticky slime that gums up a predator's mouth. They come to the surface on wet nights to hunt and retreat underground in dry weather.

Why they matter

Lungless salamanders are among the most numerous animals with backbones in eastern forests, and they eat huge numbers of the small invertebrates that break down leaf litter. They are food for snakes, birds and small mammals.

Reproduction and lifecycle

Eggs — A small clutch laid in a damp crevice or rotting log, guarded by the female
Hatching — As tiny copies of the adults; there is no aquatic larva
Young — Stay close to the nest site at first
Maturity — At three to five years
Lifespan — Over 20 years
Breathing — Through the skin; no lungs

Living around people

  • Leave logs and rocks where they lie, or put them back exactly as they were.
  • The slime is harmless but hard to wash off; there is no need to handle them.
  • Leaf litter and fallen wood left in a garden give them shelter.

Misconceptions

  • Slimy means sick. The slime is a healthy defence.
