  • Results of reduced major axis regressions of log10-transformed morphometric data against log10 of snout-vent length for ontogenetic series of the three species included in the ontogenetic scaling part. All regressions are significant at the α=0.01 level. Slopes indicated in bold are significantly different from model predictions
