From: Characterizing phenotypic diversity in marine populations of the threespine stickleback
Analysis of stickleback body shape. Panel (a) shows an image of the left side of a female stickleback body sampled from the Englishman River site, with anatomical landmarks (1–15) used for geometric morphometric analysis (see methods). Panel (b) is a thin-plate spline deformation grid which represents variation in the shape of the specimen in panel (a). The deformation grid is based on the Procrustes shape coordinates, generated from a generalized Procrustes analysis using the shape landmarks shows in panel (a) as described in the methods.
