Despite jellyfish’s ecological and socioeconomic impacts, they are still an understudied component of marine ecosystems. Even with its conspicuous size, reaching ~ 1 m in bell diameter, Drymonema gorgo has been rarely observed, with only a few occurrences in the literature, suggesting that it is not a common species. Here, we gathered historical records from literature, personal communication, and novel data from the World Wide Web (WWW) to obtain observations of D. gorgo along the Brazilian coast. A total of 63 observations from 1857 to 2022 were compiled, of which 57 were extracted from the web. Observations on this jellyfish concentrated between 22° S and 27° S, especially in the Cabo Frio region in Rio de Janeiro. They were reported throughout the year, except in August and October, with the highest concentrations in March (late summer). Based on the notable complement on information about its occurrence in the last ten years, we hypothesize that D. gorgo is probably not as rare as suggested by the near absence of previous literature records. In addition, biological associations of D. gorgo with other species were also discovered such as (1) predation on the jellyfish Aurelia sp. and Chrysaora lactea; (2) food item for the green turtle Chelonia mydas; and (3) association with fishes. This study provides evidence of the potential use of the WWW to obtain ecological data about conspicuous marine species occurrence, such as D. gorgo, helping to fill knowledge gaps and overcome difficulties in its detection using traditional methodologies.

尽管水母具有生态和社会经济影响，但它们仍然是海洋生态系统中未被充分研究的组成部分。尽管其钟形直径达到约 1 m，Drymonema gorgo 的体型十分引人注目，但它却很少被观察到，仅在文献中出现过几次，这表明它不是一个常见的物种。在这里，我们从文献、个人通讯和万维网 (WWW) 的新颖数据中收集了历史记录，以获得巴西海岸沿线D. gorgo的观测结果。共收集了 1857 年至 2022 年的 63 条观察结果，其中 57 条来自网络。对这种水母的观测集中在南纬 22° 至 27° 之间，尤其是在里约热内卢的卡波弗里奥地区。除八月和十月外，全年都有报告，其中三月（夏末）浓度最高。基于过去十年中有关其出现的信息的显着补充，我们假设D. gorgo可能并不像以前几乎没有文献记录所暗示的那样罕见。此外，还发现了D. gorgo与其他物种的生物学关联，例如（1）捕食水母Aurelia sp。和金金藻；(2)绿海龟Chelonia mydas的食物；(3) 与鱼类的关联。这项研究提供了利用 WWW 获取有关显着海洋物种出现（例如D. gorgo）的生态数据的证据，有助于填补知识空白并克服使用传统方法进行检测的困难。
