Planuloid budding from a cutting plane of polyp stalk of Cassiopea sp.(Cnidaria, Scyphozoa) [PDF]

open access: yes, 2015
Cassiopea polyps that appeared in culture vessels of Turritopsis sp. polyps at the Seto Marine Biological Laboratory, Kyoto University in 2014 were experimentally amputated their stalks from the calyxes.

Asexual reproduction strategies and blooming potential in Scyphozoa [PDF]

open access: yesMarine Ecology Progress Series, 2014
Scyphistomae show different modes of propagation, occasionally allowing the sudden release of great numbers of medusae through strobilation leading to so-called jellyfish blooms. Accordingly, factors regulating asexual reproduction strategies will control scyphistoma density, which, in turn, may influence blooming potential.

Back with a bang – an unexpected massive bloom of Cassiopea andromeda (Forskaal, 1775) in the Maltese Islands, nine years after its first appearance [PDF]

open access: yes, 2018
The upside-down jellyfish—Cassiopea andromeda (Forsskål, 1775)—is considered an established alien within the eastern Mediterranean Sea, but the species exhibits a highly sporadic occurrence further west within the basin.

Comparative muscle development of scyphozoan jellyfish with simple and complex life cycles [PDF]

open access: yes, 2015
International audienceBackground : Simple life cycles arise from complex life cycles when one or more developmental stages are lost. This raises a fundamental question - how can an intermediate stage, such as a larva, be removed, and development still ...

Haemolytic activity and characterization of nematocyst venom from Pelagia noctiluca (Cnidaria: Scyphozoa) [PDF]

open access: yes, 2013
We investigated the haemolytic capacity of the crude venom extracted from isolated nematocysts of Pelagia noctiluca (Cnidaria: Scyphozoa), and evidenced the proteic fractions responsible for this activity.

Phosphatic Biomineralization in Scyphozoa (Cnidaria): A Review

open access: yesMinerals, 2022
Phosphatic biomineralization is unknown in modern species of Scyphozoa (Cnidaria). However, some extinct groups of Scyphozoa, such as conulariids and Sphenothallus, were capable of secreting phosphatic exoskeletons. Both conulariids and Sphenothallus used apatite to improve the mechanical properties of their skeletons, which offered better protection ...

日本におけるAtorella vanhoeffeni(刺胞動物門,鉢虫綱,カンムリクラゲ目)の広範囲な地理的分布 [PDF]

open access: yes, 2012
Medusae of a rare, small scyphomedusa, Atorella vanhoeffeni Bigelow, 1909 (Cnidaria, Scyphozoa, Coronatae), were collected and/or photographed at three sites in Japan: Notojima, Ishikawa Prefecture, in the Sea of Japan; Osezaki, Shizuoka Prefecture, on ...

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 ...
