This chart was compiled by Megan Kane using turtle carapace-length data from the Vermont Reptile and Amphibian Atlas Database in June of 2013. These turtles were organized by carapace size, and include the largest 10% from each species.
The lengths in the left numerical column are those you would expect for mature adults of the larger sex (usually females) of these species in Vermont. The lengths in the middle are those for the largest, reliably-documented turtle of that species from Vermont. The right numerical column shows the number of individuals that made up the largest 10% of records for that species. Can you document a larger one?
