Of all 12 characters (carapace length and 11 ratios; Appendix C, under A), only carapace length and relative pleopod I endopodite length (pl1enex) are significantly different at p <0.001. The increase in carapace length and elongation of the endopodite, however, are both gradual with high variability within each group. Hence, no clear separation of the three female groups according to both mentioned characters could be done. Moreover, carapace length turned out to be highly sexually dimorphic, being longer in females than in males (see Appendix A).</paragraph>
