Swimming and feeding in Periphylla periphylla (Scyphozoa, Coronatae) [PDF]
Marine Biology, 2007 Some western Norwegian fjords host extraordinarily abundant and persistent populations of the mesopelagic, coronate scyphomedusa, Periphylla periphylla. In these environments, from late autumn to spring, the medusae undertake regular diel vertical migrations into surface waters.

Scientia Marina, 2001 The structure of the ovaries and testes of Nausithoe aurea, reared in the laboratory, is described to update the knowledge of coronate scyphomedusae gametogenesis and early development. The testis is similar to those of other scyphozoans.

Questioning the rise of gelatinous zooplankton in the World's oceans [PDF]
, 2012 During the past several decades, high numbers of gelatinous zooplankton species have been reported in many estuarine and coastal ecosystems. Coupled with media-driven public perception, a paradigm has evolved in which the global ocean ecosystems are ...

Not all jellyfish are equal: isotopic evidence for inter- and intraspecific variation in jellyfish trophic ecology [PDF]
, 2015 Jellyfish are highly topical within studies of pelagic food-webs and there is a growing realisation that their role is more complex than once thought.

The complete mitogenome of ghost jellyfish Cyanea nozakii (Cnidaria, Semaeostomeae, Cyaneidae)
Mitochondrial DNA. Part B. Resources, 2018 The cnidarian jellyfishes are impressive organisms to show animal mitochondrial genomic diversities. Their mitogenome structure is linear and tRNA content has one or two in numbers, which is highly different than other metazoans.

Morphological diversity of medusan lineages constrained by animal–fluid interactions [PDF]
, 2007 Cnidarian medusae, commonly known as jellyfish, represent the earliest known animal taxa to achieve locomotion using muscle power. Propulsion by medusae requires the force of bell contraction to generate forward thrust.

Ecology and Evolution, 2021 Jellyfish are useful genetic indicators for aquatic ecosystems as they have limited mobility and are highly exposed to the water column. By using comparative genomics and the molecular clock (timetree) of Rhizostoma pulmo, we revealed a divergence point ...

From single neurons to behavior in the jellyfish Aurelia aurita
eLife, 2019 Jellyfish nerve nets provide insight into the origins of nervous systems, as both their taxonomic position and their evolutionary age imply that jellyfish resemble some of the earliest neuron-bearing, actively-swimming animals. Here, we develop the first

Frontiers in Marine Science, 2022 Symbiotic scyphozoan jellyfish are poorly understood in terms of their symbionts and traits, as well as the ecological significance of this association. Dinoflagellate symbionts of the medusae Cotylorhiza tuberculata, Phyllorhiza punctata, and Cassiopea ...
