Fig. 2From: Hooked on you: shape of attachment structures in cymothoid isopods reflects parasitic strategyMorphospace plot of P1 (a) and P7 (b) dactyli. The first principal component is plotted on the x-axis and the second on the y-axis. Percentages included in the axis labels are the variation accounted for by each principal component. Convex hulls are calculated for each parasitic mode. Silhouettes are PCA backtransformations that depict shape across morphospacesBack to article page
