Compared to the morphological changes seen during the development of Leptomedusae (Weston et al.

One strategy, observed among leptomedusae and anthomedusae, is to swim via jet propulsion as juveniles (Weston et al.

Accordingly, leptomedusae, such as Mitrocoma cellularia, Aequorea victoria, and Eutonina indicans, that use jet propulsion during early developmental stages have prolate bells with narrow orifices (i.
