Fig. 6 in Molecular Systematics and Morphological Analyses of the Subgenus Setihenricia (Echinodermata: Asteroidea: Henricia) from Japan

Fig. 6. Morphological characters representing the degree of tapering of spines. A, SEM images of DS; B, ratios of DSbase/DStip; C, SEM images of AdS; D, ratios of AdSbase/AdStip. See Table 4for abbreviations. Circles on boxplots (B and D) indicate outliers. On B and D, a value above one (indicated by a vertical dashed line) can be interpreted that the spine is tapered. Enlarged images of A and C are available in the figshare repository (Wakita et al. 2019).
