Spotted Salamander (Ambystoma maculatum) - Ohio Herp Atlas

Spotted Salamander Ambystoma maculatum

Length 6 – 7 3/4 in. (15-20 cm). Spotted Salamanders are found throughout Ohio in low-lying moist woodlands adjacent to swamps, ponds, and creeks. Because of their secretive nature and their love for tunneling underground, they are seldom seen except in early spring. Then they migrate in large numbers to breeding ponds. Even then, they are active only at night. Often the only evidence of their presence is a fist-sized egg mass containing less than 100 eggs which is attached to a submerged stick or plant. How does a six-inch salamander pass a fist-sized egg mass? The eggs are not that large when laid, but the jelly-like substance that covers them swells when the eggs come in contact with the water. This large, chunky salamander has two irregular rows of yellow or greenish-yellow spots. Occasionally, the spots on the back of the head are orange.
