Figure 7. Bridging cochlea shape with audiogram data. A, examples of audiograms of the same taxa as in Figure 3 (see Supporting Information, Table S1 for audiogram sources). B, linear regression of the relative cross-section area of the first turn and CF, with a significant result for terrestrial species and the combined data of all animals. C, CF and cochlea base width are negatively correlated in terrestrial species and Caniformia in general. D, linear regression for relative cochlea centroid size and CF exhibits significant correlation for terrestrial animals and the combined dataset. E, correlation for the relative distance between the tympanic sulcus and the oval window and CF results in a clustering by habitat with very liưle overlap and clear negative correlation significant for both groups. Legend: ** = P ≤ 0.01, *** = P ≤ 0.001, **** = P ≤ 0.0001.
