Cnidarians are known to undergo reverse development as a survival mechanism against adverse environmental conditions. Polyp bail-out consists in the polyps’ detachment from the mother colony due to stressful conditions, followed by a complete tissue and cells rearrangement and in some cases in a regression into a simple, ciliated form. Here we describe a massive polyp bail-out event occurred in the mesophotic black coral Antipathella subpinnata in reared conditions. This is the first report of a bail-out event in this species providing new insights into the life cycle and ecology of black corals.

揭示黑珊瑚的无性生殖特征：Antipathella subpinnata 中的息肉救助

众所周知，刺胞动物会经历逆向发育，作为对抗不利环境条件的生存机制。息肉救助包括息肉在压力条件下从母集落脱离，然后是完整的组织和细胞重排，在某些情况下回归到简单的纤毛形式。在这里，我们描述了在饲养条件下中光黑珊瑚 Antipathella subpinnata 中发生的大规模息肉救助事件。这是该物种救助事件的第一份报告，为黑珊瑚的生命周期和生态提供了新的见解。
