Both macroscopic vertebrates and invertebrates associated with jellyfishes in Sri Lankan waters were surveyed in 2017, as their interactions had not been studied before. In the survey, young teleost fishes were observed to be swimming together with medusae of Phyllorhiza punctata, and the absence of mesoglea in the stomach contents of the teleost Carangoides praeustus confirmed that the association is not a predatory relationship, but could be commensalism. Similar swimming behaviour was observed in the teleost Gnathanodon speciosus with the medusa, Acromitus flagellatus using underwater footage. Further, an association of the brittle star Ophiocnemis marmorata with jellyfishes, Marivagia stellata and Mastigias sidereus, was also reported in this study from Sri Lankan waters, and this relationship could be kleptoparasitism. Likewise, an assemblage of a copepod, Paramacrochiron sp., with medusae of Lobonemoides gracilis and Rhopilema hispidum was known as parasitism. This study reports, for the first time, the associations of C. praeustus,–P. punctata, G. speciosus,–A. flagellatus, O. marmorata,–M. stellata, O. marmorata,– and M. sidereus.

2017 年对斯里兰卡水域中与水母相关的宏观脊椎动物和无脊椎动物进行了调查，因为之前尚未研究过它们之间的相互作用。在调查中，观察到硬骨鱼幼鱼与Phyllorhiza punctata水母一起游动，而硬骨鱼Carangoides praeustus胃内容物中缺乏中胶，证实这种关联不是捕食关系，而可能是共生关系。使用水下镜头在硬骨鱼 Gnathanodon spiosus和水母Acromitus flagellatus中观察到类似的游泳行为。此外，这项来自斯里兰卡水域的研究还报道了脆星蛇尾蛇（Ophiocnemis marmorata）与水母、Marivagia stellata和Mastigias sidereus的关联，这种关系可能是盗贼寄生。同样，桡足类Paramacrochiron sp.与水母Lobonemoides gracilis和Rhopilema hispidum的组合被称为寄生。这项研究首次报告了C. praeustus、- P. punctata、G. spiosus、- A. flagellatus、O. marmorata、- M. stellata、O. marmorata、- 和M. sidereus的关联。
