Feeding behaviour of the hydromedusa Aequorea vitrina
Scientia Marina, 2007 The prey-capture mechanism of the hydromedusa Aequorea vitrina was studied by means of laboratory video-microscope observations. In stagnant water A. vitrina remains stationary with its very long (about 4x bell diameter) marginal tentacles motionless ...

Comparative Analysis of Convergent Jellyfish Eyes Reveals Extensive Differences in Expression of Vision-Related Genes. [PDF]
Ecol EvolEyes have evolved in many different lineages, including several times within jellyfish, yet the relative contributions of shared and lineage‐specific genes to convergent eyes are not known. We find that three long‐diverged species of jellyfish have mostly divergent patterns of gene expression in their eye‐bearing tissues, suggesting a major role for ...

Hidden gems: Scattered knowledge hampered freshwater jellyfish research over the past one-and-a-half centuries. [PDF]
Ecol EvolApproximately 150 years of research on freshwater jellyfish globally have resulted in a considerable amount of information. However, this is not comprehensively available to most researchers worldwide. Scattered information allows only for a fragmented view of the research field, which mediated by climate change received increasing importance.

Planktonic associations between medusae (classes Scyphozoa and Hydrozoa) and epifaunal crustaceans [PDF]
PeerJ, 2021 Jellyfish are known to carry various epibionts, including many of the subphylum Crustacea. However, the associations between gelatinous zooplankton and other invertebrates have been chronically overlooked.

Population Structure Plays a Key Role in Community Stability. [PDF]
Ecol LettPopulation structure is a widespread yet underappreciated feature of ecological communities. Here, we develop a general theoretical framework integrating life‐stage structure into community matrix models and show that stage‐specific interactions—especially asymmetric predator‐prey dynamics—can fundamentally alter stability outcomes. Our findings reveal

Olindias deigo sp. nov., a new species (Hydrozoa, Trachylinae, Limnomedusae) from the Ryukyu Archipelago, southern Japan [PDF]
ZooKeys, 2019 A new hydromedusa belonging to the order Limnomedusae is reported from the Ryukyu Archipelago, southern Japan. Olindias deigosp. nov. can be distinguished from other Olindiidae species by the number and color of tentacles. Mature medusae of O.

Epithelial Conduction in Hydromedusae [PDF]
The Journal of General Physiology, 1968 Sarsia, Euphysa, and other hydromedusae have been studied by electrophysiological techniques and are found to have nonnervous conducting epithelia resembling those described earlier for siphonophores. Simple, nonmuscular epithelia fire singly or repetitively following brief electrical stimuli.
