Figure 4. Bone fragmentation increases SO3 surface area in cavefish.
Surface area was analyzed across groups assigned by binary scores for fragmentation and number of elements in Chica (A), Tinaja (B), and Pachón (C) cavefish. Surface area was plotted against the number of superficial neuromasts on the SO3 bone for each population in a linear regression analysis. The triangle shape represents the mean value for SO3 neuromast number and R scores indicate the correlation coefficient. Pairwise t-tests were performed and populations were grouped by statistical significance (a-b; p <0.05 = *, <0.01= **, < 0.001= ***).
