FIGURE 3 | Biplot resulting from the principal component analysis (PCA) from ecomorphological data, showing the position of 30 individuals of Inpaichthys kerri and 30 of Hyphessobrycon vilmae in the ecomorphological space, represented by the two first axis (PC1 and PC2) and analyzed from 22 ecomorphological attributes. Arrow indicates the variation of the most important attributes (see Tab. 2).
