Marbled Salamander Ambystoma opacum (Gravenhorst, 1807)  

Status:

Marbled Salamander (Ambystoma opacum) is a relatively small, black mole salamander with silvery or whitish banded markings. Unlike other Maryland representatives of the genus Ambystoma, this species breeds in late autumn at vernal pools, including ones that are seasonally dry until spring rains. The female guards her eggs until water levels rise, and the eggs hatch. This species is often found in relatively dry habitats for this genus, including sandy soils (Conant & Collins, 1998; Maryland DNR site; Virginia Herpetological Society site). Marbled Salamanders are recorded from nearly every county in Maryland, with the exception of Carroll and Garrett Counties.

There are 241 records in the project database.
