The complete mitogenome of ghost jellyfish Cyanea nozakii (Cnidaria, Semaeostomeae, Cyaneidae)

open access: yesMitochondrial 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.

From single neurons to behavior in the jellyfish Aurelia aurita

open access: yeseLife, 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

Observations on the Surface Structure of Aurelia solida (Scyphozoa) Polyps and Medusae [PDF]

open access: yesDiversity, 2021
The surface structures and mucus layers that form an interface between the epithelial layer of organisms and their external environment were studied in the bloom-forming moon jellyfish (Aurelia solida, Scyphozoa) from the northern Adriatic. The surface of the polyps revealed epithelial ciliated cells and numerous nematocysts, both non-discharged and ...

Comparative genetics of scyphozoan species reveals the geological history and contemporary processes of the Mediterranean Sea

open access: yesEcology 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 ...

JellyWeb: an interactive information system on Scyphozoa, Cubozoa and Staurozoa [PDF]

open access: yesZooKeys, 2016
Identification of organisms is traditionally based on the use of "classic" identification keys, normally printed on paper. These keys have several drawbacks: they are mainly based on the systematics, requiring identification of orders, families and genera at first; they are written by experts for other experts, in a specific scientific jargon; they ...

Diversity of Dinoflagellate Symbionts in Scyphozoan Hosts From Shallow Environments: The Mediterranean Sea and Cabo Frio (Rio de Janeiro, Brazil)

open access: yesFrontiers 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 ...

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

open access: yesJournal of Fish Biology, Volume 109, Issue 3, Page 1433-1444, September 2026.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.
