Figure 4From: The mitochondrial phylogeny of an ancient lineage of ray-finned fishes (Polypteridae) with implications for the evolution of body elongation, pelvic fin loss, and craniofacial morphology in OsteichthyesPlots of principal component (PC) and centroid size (CS) for morphometric characters of Polypterus. a) CS and PC1 for dorsal view, b) PC1 and PC 2 for dorsal view, c) CS and PC1 for ventral view, d) PC1 and PC2 for ventral view. Grouping corresponds to the clade inferred from molecular phylogenetic analysis (Fig. 2): Blue = Polypterus ansorgei, P. bichir lapradei, P. endlicheri endlicheri, and P. e. congicus; Green = P. mokelembembe; Purple = P. ornatipinnis, P. retropinnis, and P. weeksii; Red = P. delhezi, P. palmas buettikoferi, P. p. polli, P. senegalus senegalus, and P. teugelsi.Back to article page
