Figure 3

Principal components analysis illustrating the ontogenetic trajectory of Acanthurus triostegus in the shape space. Plots of the first two PCs; percentage of shape variance summarized by each PC is given in parentheses. () Larvae at settlement, (▲) Juvenile and () adult specimens. The polygons illustrate the visual discrimination of two groups in juveniles. TPS-grids illustrate shape changes associated with the first two principal components. PC1-grid and PC2-grid span across a total of 0.1 axis unit (−0.05 to 0.05) and 0.06 axis unit (−0.03 to 0.03), respectively. The shape differences have been exaggerated for better visualization (PC1: x1.5; PC2: x2.5).
