Blue-spotted Salamander

Ambystoma laterale

IdentificationPhoto by P. Wimmer

The Blue-spotted Salamander is the smallest of Vermont’s three mole salamanders.  Mole salamanders spend most of their lives underground (like moles) except when migrating to and from breeding wetlands, pools, and ponds.  They all have sturdy bodies and strong legs.  They grow to 5 inches long and are black with small light blue spots on their backs and sides.

This species has historically hybridized with Jefferson Salamanders and a wide variety of hybrids can be found. This sometimes makes identification difficult.

Pure Blue-spotted Salamanders lay single gelatinous eggs, but hybrids reportedly deposit masses with up to 12 eggs.
