Checklist of Amphibian Species and Identification Guide

Marbled Salamander, Ambystoma opacum

marbled salamander Marbled Salamander
The color pattern of the Marbled Salamander is quite consistent and unique. They have gray to white bands or markings on their sides against a black background. They are a small salamander, at least for the family Ambystomatidae, reaching lengths around 4 inches. They have a black belly and generally the females' bands are gray whereas the males' are nearly white. Marbled Salamanders are autumn breeders. In the north they lay eggs from September to October, in the south from October to December. The larvae metamorphose very early, in April or May, as a result. They mate on land and the females even lay their eggs on land in places that normally fill with water during the autumn. They guard their eggs until the site becomes flooded, at which time the eggs hatch.
