The Presence of a Substrate Strengthens The Jet Generated by Upside-Down Jellyfish

Frontiers in Marine Science, 2022
Upside-down jellyfish, Cassiopea, are prevalent in warm and shallow parts of the oceans throughout the world. They are unique among jellyfish in that they rest upside down against the substrate and extend their oral arms upwards.

Fitness of Cassiopea polyps Inoculated with Different Types of Symbionts

Ilmu Kelautan, 2022
The specificity of the relationship between cnidarian hosts and symbiotic dinoflagellates (zooxanthellae) differs among host species. Some cnidarian hosts can establish symbiotic relationship with various types of zooxanthellae, while others exhibit high

Reproducible propagation technique for the symbiotic cnidarian model system Cassiopea xamachana

Biology Open, 2022
The phylum Cnidaria is composed of corals, jellyfish, hydras, and sea anemones. Cnidarians are well-known for their regenerative capability, with many species maintaining the ability to regenerate complete structures.

Maximal use of 0.05% topical isotretinoin in patients with congenital ichthyosis results in low systemic exposure. [PDF]

Br J Clin Pharmacol
Abstract Congenital ichthyoses (CI) are rare, inherited skin disorders characterized by hyperkeratosis, scaling and fissuring that significantly impair patients' quality of life. Treatment options are limited, with systemic retinoids reserved for severe cases owing to their adverse effect profile.

The puzzling occurrence of the upside-down jellyfish Cassiopea (Cnidaria: Scyphozoa) along the Brazilian coast: a result of several invasion events? [PDF]

Zoologia (Curitiba), 2020
The massive occurrence of jellyfish in several areas of the world is reported annually, but most of the data come from the northern hemisphere and often refer to a restricted group of species that are not in the genus Cassiopea.

High photosynthetic plasticity may reinforce invasiveness of upside-down zooxanthellate jellyfish in Mediterranean coastal waters.

PLoS ONE, 2021
Ecological profiling of non-native species is essential to predict their dispersal and invasiveness potential across different areas of the world. Cassiopea is a monophyletic taxonomic group of scyphozoan mixotrophic jellyfish including C.

Benthic jellyfish act as suction pumps to facilitate release of interstitial porewater

Scientific Reports, 2023
Upside-down jellyfish, genus Cassiopea (Péron and Lesueur, 1809), are found in shallow coastal habitats in tropical and subtropical regions circumglobally.

Application of environmental DNA metabarcoding and quantitative PCR to detect blooming jellyfish in a temperate bay of northern China

Ecology and Evolution, Volume 13, Issue 11, November 2023., 2023
We developed eDNA metabarcoding and quantitative PCR for the detection and assessment of jellyfish taxa in the temperate Yantai Sishili Bay (YSB) and estimated the spatial distribution of Aurelia coerulea. Our results demonstrate the potential of two eDNA techniques in jellyfish biomass investigation and jellyfish taxa detecting.

Physiology of the widespread pulsating soft coral Xenia umbellata is affected by food sources, but not by water flow

Ecology and Evolution, Volume 13, Issue 9, September 2023., 2023
This manuscript reports on the separate and interactive effects of varying water flow regimes and feeding on the physiology of the soft coral Xenia umbellata. From our study, we concluded that X. umbellata does not receive any additional benefit from high water flow nor suffer in low flow conditions, as it may regulate autotrophy and heterotrophy via ...

Residual tissue magnesium concentration in jellyfish (Aurelia aurita and Cassiopea andromeda) following magnesium chloride euthanasia

Zoo Biology, Volume 42, Issue 5, Page 661-667, September/October 2023., 2023
The mean (±SD) magnesium (left) and calcium (right) concentrations (µg/g) in Aurelia aurita and Cassiopea andromeda following freezing (F) or 144 g/L MgCl2 bath (Mg0) and one (R1) or two (R2) subsequent baths in source water for trials 1 and 2. Tissue magnesium and calcium were significantly different between species in both trials.
