The thickness (a) and light transmittance (b) of eggshell in the four lizard species, the Chinese skink (n = 17), the northern grass lizard (n = 17), the oriental leaf-toed gecko (n = 16) and the Japanese gecko (n = 21). The line in the box is the median. Whiskers represent the 10th and 90th percentiles. Black circles beyond the boxplots show the 5th to 95th percentiles. Different alphabets above the boxes indicate significant difference (Tukey’s post-hoc test).
