Evolution in the dark: Unexpected genetic diversity and morphological stasis in the blind, aquifer-dwelling catfish Horaglanis

Figure 4.

Principal Component Analysis of multivariate morphometric data presented in Table 4. Factor scores of observations are plotted on the first two components that together explained 55.28% of the total variation in the data. Scree plot for factor loadings is provided in the inset. There were no significant morphometric differences in the three species (PERMANOVA, 9999 permutations, F = 1.576, P = 0.1064).
