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

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 ...

The first record of the white-spotted Australian jellyfish Phyllorhiza punctata von Lendenfeld, 1884 from Maltese waters (Western Mediterranean) and from the Ionian coast of Italy [PDF]

open access: yes, 2017
The occurrence of the white-spotted Australian jellyfish Phyllorhiza punctata Lendenfeld, 1884, an Indo-Pacific scyphozoan species mainly restricted to the Levantine Basin, is hereby reported for the first time from Maltese waters (western ...

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.

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 ...

Jellyfish (Chrysaora lactea, Cnidaria, Semaeostomeae) aggregations in southern Brazil and consequences of stings in humans

open access: yesLatin American Journal of Aquatic Research, 2014
The frequency of jellyfish blooms is generating a world-wide discussion about medusae population explosions, mainly those associated with stings. We report over 20,000 envenomations caused by Chrysaora lactea (Scyphozoa) in the State of Paraná (southern ...
