Ambystoma opacum seems to be the most common of the mole salamanders in my area. I find them sometimes in the fall, on roads, or under logs. They breed in fall (and winter?) in my area. This one was under a log along a woodland trail. It was captured and posed for a photo session, then released. I measured the length in another photo adjacent to a scale--about 11 cm, with about 4 cm of that being the tail.
