Behaviour

Spotted salamanders spend most of the year in burrows. On the first warm, rainy nights of winter they migrate to the same woodland pools where they hatched, sometimes in large numbers. Their eggs often turn green from algae living inside them, which help supply oxygen.

Why they matter

They are a large part of the animal life of eastern forests, eating invertebrates in the soil. The alga that lives in their eggs, and even in their cells, is one of the few known partnerships of its kind in animals with backbones.

Reproduction and lifecycle

Eggs — Clumps of 50 to 250 in firm jelly, attached to twigs in pools
Hatching — In one to two months
Larvae — Gilled; change in two to four months
Maturity — At a few years
Lifespan — Over 20 years
Migration — To the pool where they hatched

Living around people

  • On rainy winter nights near woodland pools, drive slowly and watch for salamanders on the road.
  • A salamander on a road can be carried across in the direction it was heading, with wet hands.
  • Woodland pools that dry in summer are easily filled; they are where these salamanders breed.

Misconceptions

  • Salamanders are lizards. They are amphibians, with moist skin and no scales.
