This is likely to be linked to A. aurita, Cyanea lamarckii and
Cyanea capillata having distinct ecological differences (Russell,
1970; Doyle et al., 2007): for example, the growth and strobilation
of their polyps are not affected the same way by variations of
temperature and salinity (laboratory studies suggested that cold
winter temperatures inhibit the strobilation of A. aurita polyps
whereas it promotes strobilation in C. capillata) (Holst and Jarms,
