Marbled Salamander, Ambystoma opacum
 |
| 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. |
