Statistical comparisons comparing the dorsal, left- and right-lateral heads for several features reveal significant trends based on eye morphology. We examined the non-parametric statistical relationship between neuromast features comparing normal-eyed (orange), micro-eyed (yellow) and eyeless (blue) Sinocyclocheilus across the dorsal, left-lateral and right-lateral heads (a,c,e). Additionally, we compared non-parametric statistical test values within each morphology group focusing on the dorsal (red), left (grey) and right (green) aspects (b,d,f). The neuromast features included the number of superficial neuromasts (a,b), the mean distance between neuromasts (c,d) and the area of the head populated by neuromasts (e,f). *: p < 0.05, **: p < 0.01 and ***: p < 0.001.
