FIGURE 51. PCA plots of measurements relative to total length and their relationships to each other. Points indicate the average principal component (PC) scores with standard error bars. Lines indicate the eigenvector scores for each measurement. A. Disc length (DL), disc width (DW), and snout to maximum disc width (SDW); B. snout to maximum disc width, head length (HDL), preorbital length (POB), and preoral length (POR); C. first dorsal fin total length (DIT), first dorsal fin height (D1H), first dorsal fin base length (D1B), second dorsal fin height (D2H), second dorsal fin base length (D2B), caudal fin height (CDH), and caudal fin base length (CDB); D. pelvic fin anterior lobe length (PPL), pelvic fin anterior lobe inner length (PAL), and pelvic fin posterior lobe length (IAL); E. total length (TL), disc length, disc width, interdorsal space (IDS), and tail length (TAL); F. spiracle length (SPL), interspiracular space (ISP), and interorbital width (IOW). Species shown by color: Bathyraja abyssicola (red triangle), B. aleutica (green triangle), B. interrupta (maroon hexagon), B. kincaidii (blue circle), B. microtrachys (pink star), B. spinosissima (yellow diamond), and B. trachura (black square).
