  1. Median values of the variances of the six main axes for 29 populations (237 specimens) from shallow and for 38 populations (312 specimens) from steep shores are presented for the six main axes describing variation in meristics and shape. Values in bold are significant at the 0.05 level in non-parametric Mann-Whitney U tests
