Journal of Oceanology and Limnology, 2020 Aurelia spp. ephyrae have been reported to form blooms in sea cucumber aquaculture ponds in the Bohai and Yellow Seas. To identify the species, we carried out a genetic analysis of Aurelia spp.

Starvation of the Respiratory Metabolism and Locomotion of Aurelia aurita s.l. Ephyrae
Open Journal of Marine Science, 2021 Blooms of the scyphozoan jellyfish Aurelia aurita are greatly regulated by the survival rate of planktonic ephyrae. The ecophysiology of ephyrae is poorly studied compared with polyps and medusae. As extremely strong starvation resistance and recovery capability of A.

Morphological characteristics of ephyrae of Aurelia coerulea derived from planula strobilation [PDF]
Fisheries Science, 2021 AbstractEphyrae are produced through the strobilation of polyps in the general life cycle of Aurelia coerulea. However, it has been reported that planulae can also metamorphose directly into ephyrae, without passing through the polyp stage. There is a mixture of ephyrae developed from planulae (planula-strobilated ephyrae) and ephyrae developed from ...

Double Monster Ephyrae of Aurelia aurita
Nature, 1957A NORMAL scyphistoma, taken with many others from a tank in the aquarium of the Marine Station at Millport, produced numerous normal ephyrae and two double monsters.

Graviceptor development in jellyfish ephyrae in space and on earth
Advances in Space Research, 1994Graviceptor (rhopalium) development in Aurelia aurita ephyrae which developed on Earth and in space during the nine-day NASA SLS-1 mission was compared. The space-developed ephyrae made graviceptors which were morphologically similar to those of their ground-based controls.

Ephyra jellyfish as a new model for ecotoxicological bioassays
Marine Environmental Research, 2014The aim of this study was a preliminary investigation on the possibility of using the ephyra of Scyphozoan jellyfish Aurelia aurita (Linnaeus, 1758), the common moon jellyfish, as an innovative model organism in marine ecotoxicology. A series of sequential experiments have been carried out in laboratory in order to investigate the influence of ...

Effect of neurotoxic compounds on ephyrae of Aurelia aurita jellyfish
Hydrobiologia, 2015The aim of this study was to analyze the toxicity of two neurotoxic compounds on the ephyra stage of the Scyphozoan jellyfish Aurelia aurita, an innovative and sensitive model organism recently proposed in ecotoxicological bioassays. Indeed, jellyfish play an important role in the marine ecosystem, being a key component of the gelatinous zooplankton ...

The morphogenesis of ephyra in Coronatae (Cnidaria, Scyphozoa)
Marine Biology, 2007The morphogenesis of ephyrae of Atorella vanhoeffeni Bigelow, 1909 (Werner, 1967) and of Nausithoe maculata Jarms, 1990 during strobilation is described. We found differences in the developmental pattern of marginal structures and structural changes of longitudinal muscle tubes in particular.

Rhopalium development in Aurelia aurita ephyrae
Hydrobiologia, 1991Rhopalia of developing ephyrae were examined using the SEM and TEM at 24 h intervals following strobilation induction. Kinocilia are shorter in the ephyra stage than in polyps. A few ephyra-type kinocilia are found in rhopalia as early as 24 h after induction, before a distinct rhopalium is seen.
