The maternalzygotic transition and zygotic activation of the Mnemiopsis leidyi genome occurs within the first three cleavage cycles. This map was computer-generated and has not yet been reviewed.

Cydippids typically swim a looping pattern, saturating the local water column with colloblast lined tentacles and tentilla to maximize prey capture, Presnell, J.S., Bubel, M., Knowles, T. et al. 2, 204215 (1895).

These comb plates are the largest known ciliary structures in the animal kingdom, and ctenophores are the largest animals that swim by means of cilia. A rapid 3-week egg-to-egg generation time makes Mnemiopsis suitable for a wide range of experimental genetic, cellular, embryological, physiological, developmental, ecological and evolutionary studies.
