FIG. 4. Results of principal component analysis (PCA) of meristic trait data for five species of Artedidraco and two species of Neodraco. (A) Biplot visualization of PC axes 1 and 2. (B) Visualization of variable loadings for all PC axes 1, 2, and 3. Points and convex hulls in biplots are colored according to species. In panel B, D1 ¼ first dorsal-fin spines, D2 ¼ second dorsal-fin rays, A ¼ anal-fin rays, P ¼ pectoral-fin rays, and ULL ¼ tubular scales in upper lateral line.
