Figure 5.

The area, number and mean distance between neuromasts across four clades of Sinocyclocheilus reveal deep trends in sensory lateralization. Our comprehensive analyses examined the number of neuromasts on the head in the dorsal (a), left-lateral (b) and right-lateral aspects (c). Additionally, we compared the mean distance between neuromasts in the dorsal (d), left-lateral (e) and right-lateral aspects (f). Finally, we compared the head areas populated by neuromasts on the dorsal (g), left-lateral (h) and right-lateral aspects (i). Normal-eyed fishes are represented in white, micro-eyed fishes in yellow and eyeless fishes in blue histograms (mean value = asterisks, ends of histograms = s.d.). (Online version in colour.)
