FIGURE 6. Marenzelleria sp. morphometric relationships. A, arithmetic difference between anterior position of hooded hooks in noto- and neuropodia (DHH-VHH) referring to the number of the first hook-bearing chaetiger) versus total number of chaetigers. B, arithmetic difference between anterior position of hooded hooks in noto- and neuropodia (DHH-VHH) versus distribution of branchiae (referring to the number of the last branchiate chaetiger). C, arithmetic difference between the number of last branchiate chaetiger and anterior position of hooded hooks in notopodia (Br-DHH) versus total number of chaetigers. D, arithmetic difference between the number of last branchiate chaetiger and anterior position of hooded hooks in notopodia (Br- DHH) versus distribution of branchiae. E, arithmetic difference between the number of last branchiate chaetiger and anterior position of hooded hooks in neuropodia (Br-VHH) versus total number of chaetigers. F, arithmetic difference between the number of last branchiate chaetiger and anterior position of hooded hooks in neuropodia (Br-VHH) versus distribution of branchiae. Correlation coefficients (r) and their significance are reported in Table S7.
