Protective effect of Aurelia aurita against free radicals and streptozotocin-induced diabetes

open access: yesBangladesh Journal of Pharmacology, 2018
The present work was carried out to identify the anti-oxidant and anti-diabetic activities of Aurelia aurita. The chemical profiling analysis showed that it possess different biologically active secondary metabolites like phenols, alakoids, steroids etc.

Flexible margin kinematics and vortex formation of Aurelia aurita and Robojelly. [PDF]

open access: yesPLoS ONE, 2014
The development of a rowing jellyfish biomimetic robot termed as "Robojelly", has led to the discovery of a passive flexible flap located between the flexion point and bell margin on the Aurelia aurita.

Preliminary Results of the in Vivo and in Vitro Characterization of a Tentacle Venom Fraction from the Jellyfish Aurelia aurita [PDF]

open access: yesToxins, 2013
The neurotoxic effects produced by a tentacle venom extract and a fraction were analyzed and correlated by in vivo and in vitro approaches. The tentacle venom extract exhibited a wide range of protein components (from 24 to >225 kDa) and produced ...

Fatty acids as the main energy source in polyps of the jellyfish (Cnidaria: Aurelia aurita) for survival strategy under overpopulation: insights from compound-specific isotope analysis

open access: yesProgress in Earth and Planetary Science
Jellyfish exhibit an extraordinary survival strategy in high-density populations that exceed the carrying capacity of ecosystems. It is particularly questionable how jellyfish can thrive in habitats where the concentration of toxic nitrogenous waste (i.e.

Negative and positive interspecific interactions involving jellyfish polyps in marine sessile communities [PDF]

open access: yesPeerJ, 2023
Sessile marine invertebrates on hard substrates are one of the two canonical examples of communities structured by competition, but some aspects of their dynamics remain poorly understood.

DEVELOPMENTAL ASPECTS OF STROBILATION IN AURELIA AURITA [PDF]

open access: yesPublications of the Seto Marine Biological Laboratory, 1973
Strolibation in Scyphozoa has been well known as a process to produce ephyrae. This process might include the basic aspect to understand the mechanism of cellular differentiation and transformation for the particular pattern of metamorphosis.

DNA Barcoding of Moon Jellyfish (Cnidaria, Scyphozoa, Ulmaridae, Aurelia): Two Cryptic Species from the Azores (NE Atlantic, Macaronesia), and Evaluation of the Non-Indigenous Species (NIS)

open access: yesDiversity, 2023
Moon jellies are some of the most popular, widely distributed, and best-studied marine jellyfish. By the end of the past century only two or three Aurelia species were recognized, but with the rise of DNA barcoding studies, around thirty Aurelia species ...

Life History and Environment of Aurelia aurita

open access: yesLife History and Environment of Aurelia aurita
We investigated the seasonal occurrence, growth, age, and life history of Aurelia aurita in the Taniyama area of Kagoshima Bay, also some of the environmental factors such as the specific gravity, pH and the temperature, influence the appearance of Aurelia aurita in the surface layer. The size of an individual depends on environmental factors.

Non-social behavior in Aurelia aurita [PDF]

open access: yes
Non-social behavior is defined as actions or activities that are not oriented towards society or community, and interaction or relationships. This experiment demonstrates the way Aurelia aurita, otherwise known as moon jellyfish, conducts themselves towards other moon jellyfish in closed environments.
