FIGURE 8.

Morphometric features of the protractor muscle of five mochokid catfish. Data (i.e., residuals of the linear regression against standard length when it was significant or log‐transformed values when the linear regression was not significant) distributions (left) and effect sizes (right) computed from pair comparisons with Synodontis nigriventris (zero on the Y axis) for midline length, thickness, and mass of protractor muscle.
