Ellipse ratios in 18 talpid species and 2 outgroups. The box plot shows the full distribution of ellipse ratios for non-fully fossorial and fully fossorial talpid taxa: median, quartiles, and extreme values. Boxes represent the interquartile range that contains 50% of values (range from the 25th to the 75th percentile). The line across the box indicates the median. The whiskers represent maximum and minimum values. Extinct taxa were not included in the comparison, but were plotted as separate dots next to the boxes.
