Scyphozoans display a high level of developmental plasticity, including asexual reproductive strategies in their polyps. Irrespective of the alternating medusa-polyp life cycle, life stages or even complete generations can be omitted, occasionally or consistently, in some species. For example, ephyrae can be produced directly by planulae, leaving out the polyp generation, and polyps can produce free-swimming planula-like propagules, thus bypassing the medusa generation. Here, we raised Chrysaora plocamia polyps under unusually high, naturally occurring temperatures, which resulted in these polyps being unable to strobilate but able to form podocysts. Early excysts that hatched from these podocysts produced ephyrae in a premature type of strobilation. This developmental shortcut, previously unknown in scyphozoan life cycles, is described in the present report.

子夜蛾显示出高水平的发育可塑性，包括息肉中的无性生殖策略。在某些物种中，不论美杜莎息肉的生命周期如何交替，生命阶段甚至完整世代都可以被忽略。例如，e可以直接由浮萍产生，而没有息肉的产生，息肉可以产生自由游动的浮游状的繁殖体，从而绕开了美杜莎的产生。在这里，我们提出了C hrysaora plocamia息肉处于异常高的自然温度下，这导致这些息肉无法稳定但能够形成囊泡。从这些囊泡中孵出的早期囊肿会产生过早的裂形式的e。在本报告中描述了这种发育捷径，以前在后生动物的生命周期中是未知的。
