GSL-Scyphozoa-Hydrozoa-Staurozoa.pdf

open access: yes, 2022
A mini-poster of the principal jellies and hydrozoans that may be expected on biodiversity surveys in Gulf of St. Lawrence (GSL). Updated from a page of a series here: Nozères (2022) Mini-posters of macroinvertebrates in captures from bottom trawl surveys of the estuary and northern Gulf of St.

Indoles induce metamorphosis in a broad diversity of jellyfish, but not in a crown jelly (Coronatae). [PDF]

open access: yesPLoS ONE, 2017
Many animals go through one or more metamorphoses during their lives, however, the molecular underpinnings of metamorphosis across diverse species are not well understood.

A fragmented metazoan organellar genome [PDF]

open access: yes, 2008
Background: Animal mitochondrial (mt) genomes are characteristically circular molecules of ~16–20 kb. Medusozoa (Cnidaria excluding Anthozoa) are exceptional in that their mt genomes are linear and sometimes subdivided into two to presumably four ...

Swimming and feeding in Periphylla periphylla (Scyphozoa, Coronatae) [PDF]

open access: yesMarine 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.

Sexual reproduction of Nausithoe aurea (Scyphozoa, Coronatae). Gametogenesis, egg release, embryonic development, and gastrulation

open access: yesScientia 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.

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.

Mitochondrial genome of the freshwater jellyfish Craspedacusta sowerbyi and phylogenetics of Medusozoa.

open access: yesPLoS ONE, 2012
The 17,922 base pairs (bp) nucleotide sequence of the linear mitochondrial DNA (mtDNA) molecule of the freshwater jellyfish Craspedacusta sowerbyi (Hydrozoa, Trachylina, Limnomedusae) has been determined.

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 ...

Pelagic population dynamics of Aurelia sp in French Mediterranean lagoons [PDF]

open access: yes, 2015
The pelagic dynamics of the cosmopolitan scyphozoan Aurelia sp. was investigated in three French Mediterranean lagoons, Thau, Berre and Bages-Sigean, which harbour resident populations.

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 ...
