Flow Structure and Transport Characteristics of Feeding and Exchange Currents Generated by Upside-Down Cassiopea Jellyfish [PDF]

, 2012
Quantifying the flows generated by the pulsations of jellyfish bells is crucial for understanding the mechanics and efficiency of their swimming and feeding. Recent experimental and theoretical work has focused on the dynamics of vortices in the wakes of

Dart formation in nematocysts of the sea anemone Metridium senile (Linnaeus, 1761) (Cnidaria: Anthozoa)

Scientia Marina, 2010
In examining large acontia b-mastigophore and p-amastigophore nematocysts of the sea anemone Metridium senile (Linnaeus, 1761) darts were observed by interference-contrast light microscopy (LM) and scanning electron microscopy (SEM). The darts consist of

Carybdea branchi, sp. nov., a new box jellyfish (Cnidaria: Cubozoa) from South Africa. [PDF]

, 2009
A common and conspicuous member of the medusan fauna of South Africa has been the subject of repeated taxonomic confusion. After having been mistakenly identified by earlier workers as either Carybdea alata or Tamoya haplonema, this large and colourful ...

To Pee, or Not to Pee:A Review on Envenomation and Treatment in European Jellyfish Species [PDF]

, 2016
There is a growing cause for concern on envenoming European species because of jellyfish blooms, climate change and globalization displacing species. Treatment of envenomation involves the prevention of further nematocyst release and relieving local and ...

Low Ectoparasite Loads and Interactions With Cleaner Fish Among Amphiprion Anemonefish

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Interactions between ectoparasites, reef fishes and cleaner species are well documented; however, anemonefishes (Amphiprioninae) have been largely overlooked in this context. A hypothesis proposed as early as 1869 suggests that anemonefishes may experience reduced ectoparasite loads due to their symbiotic association with venomous host sea ...

Small jellyfish, large consequences: The overlooked predatory role of hydromedusae in subtropical estuarine ecosystems

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Hydromedusae are often overlooked in pelagic trophic ecology compared to large scyphozoans. We investigated the diet, prey selectivity, ingestion rates, digestion times, and predation impacts of the native Liriope tetraphylla and non‐indigenous species Cnidostoma fallax and Moerisia inkermanica in a subtropical estuary of the southwestern ...

Functional Characteristics of Nematocysts Found on the Scyphomedusa Cyanea Capillata [PDF]

, 2007
Although prey capture by cnidarians is mediated through nematocysts, their influence on prey selection by cnidarians remains poorly documented. The difficulty in visualizing nematocyst–prey interactions remains the chief obstacle to understanding how the
