The Comb Jelly Opsins and the Origins of Animal Phototransduction [PDF]
Genome Biology and Evolution, 2014 Opsins mediate light detection in most animals, and understanding their evolution is key to clarify the origin of vision. Despite the public availability of a substantial collection of well-characterized opsins, early opsin evolution has yet to be fully ...

Cannibalism makes invasive comb jelly, Mnemiopsis leidyi, resilient to unfavourable conditions [PDF]
Communications Biology, 2020 The proliferation of invasive marine species is often explained by a lack of predators and opportunistic life history traits. For the invasive comb jelly Mnemiopsis leidyi, it has remained unclear how this now widely distributed species is able to ...

Nervous systems: Neuropeptides define enigmatic comb-jelly neurons
Current Biology, 2021 The apparently simple nerve net of comb-jellies has long intrigued biologists. A new study identifies multiple unique neuropeptides in the comb-jelly nervous system and exploits these as indicators of neuronal identity and morphology.

A ctenophore (comb jelly) employs vortex rebound dynamics and outperforms other gelatinous swimmers. [PDF]
R Soc Open Sci, 2019 Gelatinous zooplankton exhibit a wide range of propulsive swimming modes. One of the most energetically efficient is the rowing behaviour exhibited by many species of schyphomedusae, which employ vortex interactions to achieve this result.

Cambrian Sessile, Suspension Feeding Stem-Group Ctenophores and Evolution of the Comb Jelly Body Plan [PDF]
Current Biology, 2019 The origin of ctenophores (comb jellies) is obscured by their controversial phylogenetic position, with recent phylogenomic analyses resolving either sponges or ctenophores as the sister group of all other animals.

Salinity Gradient of the Baltic Sea Limits the Reproduction and Population Expansion of the Newly Invaded Comb Jelly Mnemiopsis leidyi [PDF]
PLoS ONE, 2011 The recent invasion of the comb jelly Mnemiopsis leidyi into northern European waters is of major public and scientific concern. One of the key features making M. leidyi a successful invader is its high fecundity combined with fast growth rates. However,

Invasion of Danish and Adjacent Waters by the Comb Jelly Mnemiopsis leidyi—10 Years After [PDF]
Open Journal of Marine Science, 2017 The invasive ctenophore Mnemiopsis leidyi, which comes from North America’s east coast, was observed in Danish waters for the first time in 2007. Since then, the new invader has every summer spread in Danish and adjacent waters (i.e.

Mechanisms behind the metabolic flexibility of an invasive comb jelly
Journal of Sea Research, 2014 Mnemiopsis leidyi is an invasive comb jelly which has successfully established itself in European seas. The species is known to produce spectacular blooms yet it is holoplanktonic and not much is known about its population dynamics in between. One way to gain insight on how M. leidyi might survive between blooms and how it can bloom so fast is to study

Effects of pulsed magnetic fields on cilia of comb jelly [PDF]
AIP Advances, 2019 Marine comb jellies utilize cilia, arrays of bundled protein microtubules, for propulsion in water. Previous studies have reported on the orientation of the microtubules in steady electric and magnetic fields.

Microbiota differences of the comb jelly Mnemiopsis leidyi in native and invasive sub-populations [PDF]
Frontiers in Marine Science, 2019 The translocation of non-indigenous species around the world, especially in marine systems, is a matter of concern for biodiversity conservation and ecosystem functioning.
