Table 1.

Correlation table for all morphological variables for Hynobius sp. specimens. We conducted a Person correlation test for all morphological variables included in the analyses (n = 293). Each variable was measured three times and averaged, and data are presented in the form of a ratio with the focal variables divided by SVL. Significant variables are in bold, and abbreviations are explained in text and in Table 3.
