This chart was compiled by Michael Iacchetta using salamander-length data from the Vermont Reptile and Amphibian Atlas Database in April of 2014. The total length of a salamander is measured from the tip of the snout to the tip of the tail. The longest 10% of each Vermont salamander species was averaged to determine the average adult total length. For species with sample sizes over 1000, only the largest 1% were included. Those species are marked with an asterisk after the species name. The hybrid groups associated with Jefferson and Blue-spotted Salamanders were separated from the pure individuals of each species.
The lengths in the left numerical column are those you would expect for mature adults of these species in Vermont. The right numerical column shows the number of individuals that made up the sub-sample for that species. The lengths in the middle are those for the largest, reliably-documented frog of that species from Vermont. Can you document a larger one?
