Summary ⁷

The marbled salamander (Ambystoma opacum) is a species of mole salamander found in the eastern United States.

Description ⁸

This salamander is sexually dimorphic. Both males and females have black dorsal ground coloring; the bands on the female are gray or silver, while those on the male are white. The sides and the venter are black as well. They are generally short-tailed, stocky, and broad-headed (Bartlett & Bartlett 1999).

A. opacum is the most strongly dimorphic of the ambystomatids. They are capable of burrowing, but they prefer to remain closer to the surface except for seasons of extended drought (Bartlett & Bartlett 1999).
