The freshwater cnidarian Craspedacusta sowerbii Lankester 1880, has invaded lakes and ponds as well as artificial water bodies throughout the world. The first record in Uruguay corresponding to the jellyfish was made in 1961 in two artificial fountains, with no mention of the polyp form. Although local reports of other related polyp species have been made, information on the benthic form of C. sowerbii is lacking. Here we report the finding of live frustules, solitary individuals, medusae and colonies from a natural lagoon in August 2010, allowing us to observe the morphology and behavior of the polyp stage in captivity. In addition, molecular identification and remarks on the potencial path of introduction are presented. This is the first record in Uruguay of both polyp and medusa stages of C. sowerbii in a natural water body, Del Medio Lagoon (Dpto. de Florida), Uruguay.
淡水刺胞动物桃花水母（Craspedacusta sowerbii Lankester，1880年）已侵入世界各地的湖泊、池塘以及人工水体。乌拉圭的首次记录是1961年在两个人造喷泉中发现了这种水母，当时未提及水螅体形态。尽管有关于其他相关水螅体物种的本地报道，但关于桃花水母底栖形态的信息仍然缺乏。在此，我们报告2010年8月在一个天然泻湖发现了活的虫体、单独个体、水母体和群体，这使我们能够在圈养条件下观察水螅体阶段的形态和行为。此外，还介绍了分子鉴定以及关于其潜在引入途径的说明。这是乌拉圭首次在天然水体——乌拉圭佛罗里达州德尔梅迪奥泻湖记录到桃花水母的水螅体和水母体阶段。
