摘要

每年都有报道称，世界上有几个地区大量出现水母，但大多数数据来自北半球，通常指的是不属于仙桃属的一组有限物种。本研究记录了大量的无性繁殖和非本地仙后座种群，并讨论了导致这些生物入侵巴西海岸的可能情况。研究结果表明，这种水母可能曾多次入侵巴西海岸。

The puzzling occurrence of the upside-down jellyfish Cassiopea (Cnidaria: Scyphozoa) along the Brazilian coast: a result of several invasion events?

The massive occurrence of jellyfish in several areas of the world is reported annually, but most of the data come from the northern hemisphere and often refer to a restricted group of species that are not in the genus Cassiopea. This study records a massive, clonal and non-native population of Cassiopea and discusses the possible scenarios that resulted in the invasion of the Brazilian coast by these organisms. The results indicate that this jellyfish might have invaded the Brazilian coast multiple times.
