Mechanical performance of zebrafish caudal fin bony rays. (A) Procedure steps to obtain the caudal fin's slices for mechanical evaluation. Box‐plots with means (red horizontal line) and median (black horizontal line) of the E_r (B) and H (C) obtained from proximal and distal parts of fins with a triboindenter. Capital letters indicate significant statistically difference between the different regions (proximal and distal) within the same treatment (p < .01). Lowercase letters indicate significant statistically difference between the same region (proximal or distal) among different treatments (p < .01). The average values of the proximal parts of both E_r (D) and H (E) plotted against the Ca/P ratio. The regression lines show a weak but positive correlation between the variables.
