Figure 2. Cavefish have smaller SO3 bones than surface fish.
Surface area (mm2) was measured on 3D surface files of segmented SO3 bones from micro-computed tomography (Micro-CT) scans (A). Inter-fragment space is devoid of calcified tissue (B). Volume-rendered micro-CT images for Surface, Chica, Tinaja and Pachón specimens are shown with a 3D generated surface of the SO3 (C; pseudo-colored in green). Pairwise t-tests were performed and populations were grouped by statistical significance (a-c).
