淡水水螅水螅提供了位置信息梯度和再生过程的教科书实验演示。因此，发育生物学家对水螅很熟悉，但可能没有意识到它是水螅纲中相对简单的成员，水螅纲是一群主要是海洋刺胞动物，具有复杂多样的生命周期，表现出广泛的表型可塑性和再生能力。水螅动物物种为解决整个动物界的许多相关发育机制提供了广泛的机会。在这里，我们回顾了非水螅水螅动物（水螅水母、水螅和管水母动物）的最新研究成果，揭示了卵子发生、胚胎模式、同种异体识别、干细胞调节和再生的机制。我们还强调了潜在的研究方向，其中水螅多样性可以阐明微观和宏观进化时间尺度上发育过程的进化。
The fresh water polyp Hydra provides textbook experimental demonstration of positional information gradients and regeneration processes. Developmental biologists are thus familiar with Hydra, but may not appreciate that it is a relatively simple member of the Hydrozoa, a group of mostly marine cnidarians with complex and diverse life cycles, exhibiting extensive phenotypic plasticity and regenerative capabilities. Hydrozoan species offer extensive opportunities to address many developmental mechanisms relevant across the animal kingdom. Here we review recent work from non-Hydra hydrozoans - hydromedusae, hydroids and siphonophores - shedding light on mechanisms of oogenesis, embryonic patterning, allorecognition, stem cell regulation and regeneration. We also highlight potential research directions in which hydrozoan diversity can illuminate the evolution of developmental processes at micro-and macro-evolutionary time scales.
