Spotted Salamander (Ambystoma maculatum)
by Wetlands Education Team

The Spotted Salamander is a member of the mole salamander family. Mole salamanders have well developed lungs. Other members of the family are the Jefferson ’s and tiger salamanders. The Spotted Salamander grows to about 6” long, and is black in color. It has yellow and orange spots on its body. It can live for 20 years. The most interesting part of the Spotted Salamander’s lifecycle is its breeding pattern.

During March and April, Spotted Salamanders return to the vernal pool where they were born and lay up to 100 eggs, on a leaf or underwater stick. Water is absorbed by the eggs, until they reach about the size of a fist. The larvae hatch in 4 to 7 weeks, and spend the next 2 to 4 months in the vernal pools becoming land living adults. As adults, they live in moist woodlands and can be found under rocks and near swamps, ponds and creeks. They eat insects, earthworms and, they love to eat mosquito larvae, and thus help with insect control.

Vernal pools are small wetlands that dry up at least part of the year. Spotted Salamanders can thrive in vernal pools because fish cannot live there.

Spotted Salamanders have been observed everywhere in Ohio except a small bluegrass area in Ohio in Adams County where soil and bedrock conditions do not allow them to survive.

If you see a vernal pool near you, take a few minutes to study the diverse life that lives there. There is a whole world to discover! Never fill a vernal pool in with dirt. Many salamanders return to the same pool where they were born to lay their eggs.

This information has been provided by the Wetlands Education Team (WET), students from West Geauga Local Schools working to preserve wetlands in Ohio. WET is advocating to have the Spotted Salamander designated as Ohio’s state amphibian.
