Figure 6. Cavefish without SO6 bones have smaller eye orbits.
Normalized eye orbit diameter was recorded for Chica, Tinaja and Pachón cavefish (A). Volume-rendered micro-CT of representative Pachón cavefish with an SO6 bone (highlighted orange) and without an SO6 bone (gray window) are shown with eye orbits highlighted in blue (B). Pairwise t-tests were performed and populations were grouped by statistical significance (p <0.05 = *, <0.01= **, < 0.001= ***).
