FIGURE 2 in On the diversity of the genus Pisione (Polychaeta, Pisionidae) along the Portuguese continental shelf, with a key to European species

FIGURE 2. Classification (A) and Principal Coordinates Analysis (B) based on morphological descriptors of the Pisione species occurring in the Portuguese continental shelf. Descriptors are represented as vectors. W10—width at chaetiger 10; CP2/ CP3—ratio between the length of the dorsal cirri of parapodia 2 (CP2) and parapodia 3 (CP3); nrT—number of teeth of the supra-acicular chaetae; P1—protruding length of the notoaciculae; IA—presence/absence of infra-acicular simple chaetae.
