Plethodon dorsalis


on April 18th I traveled to Mammoth caves national parks as a residence hall event for the violet city cave tour but we got there a little early, so a group of us decided to follow some trails near the visitor center. After a couple of us curious students turned over some logs near the trail and came across these Plethodon dorsalis or the northern zigzag salamander. These guys are usually about 35 mm long once they are mature. The northern zigzag reproduces terrestrially and females can be observed staying with the eggs through the summer season. This species reaches reproductive maturity after about three years of age.Overall it was exciting to find a species that can not be found in Oxford Ohio.
