Regarding morphometric relationships (Table 3), variation between
studies was observed, particularly for larger medusae
(Figure A-2). For example, it seems that Aurelia aurita medusae
above 20 cmin bell diameter could be expected to achieve a greater
mass in both Norwegian and Baltic waters than in the Irish Sea
(Båmstedt et al., 1994). In a same way, Norwegian Cyanea capillata
measured by Båmstedt et al. (1994) were heavier than Irish Sea
