Nervous systems: Neuropeptides define enigmatic comb-jelly neurons
Current Biology, 2021The 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.

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

The Warty Comb Jelly in the Black Sea
2017The warty comb jelly is a zooplankton-feeding species of tentaculate ctenophore native to western Atlantic coastal waters. In the early 1980s, it came to the Black Sea, probably with ballast water from the US East Coast. In 1988, it was already common everywhere, and in 1989, the population exploded reaching a biomass that approached 1 billion tons wet

Fluid dynamics of cilia on a comb jelly
Scilight, 2019 Understanding how marine animals interact with their surrounding fluid via hairy structures known as cilia may lead to biomimetic applications in fluid transport and mixing.

The Comb Jelly Mnemiopsis Leidyi in the Black Sea
2002Following its transportation in ballast waters, the western Atlantic ctenophore Mnemiopsis leidyi caused a striking damage to the ecosystem of the Black Sea in the early 1990s. The concentration of food Zooplankton and simultaneously catches of anchovy and other pelagic fishes sharply decreased during the peak levels of the ctenophore.

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. North Sea, Limfjorden, Skagerrak, Kattegat, Belt Sea, Baltic Sea).

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. Fossil taxa can provide morphological evidence that may elucidate the origins of derived characters and shared ancestries among divergent ...

No surprise that comb jellies poop
Science, 2016As one of the organizers of the recent meeting on comb jellies (ctenophores), I feel obliged to comment on the News In Depth story “Comb jelly ‘anus’ guts ideas on origin of through-gut” (A. Maxmen, 25 March, p.

The phylogenetic position of the comb jellies (Ctenophora) and the importance of taxonomic sampling
Cladistics, 2004AbstractThe transition to a vermiform body shape is one of the most important events in animal evolution, having led to the impressive radiation of Bilateria. However, the sister group of Bilateria has remained obscure. Cladistic analyses of morphology indicate that Ctenophora is the sister group of Bilateria.

Comb Jellies (Ctenophora): A Model for Basal Metazoan Evolution and Development
Cold Spring Harbor Protocols, 2008INTRODUCTIONCtenophores, or comb jellies, are a group of marine organisms whose unique biological features and phylogenetic placement make them a key taxon for understanding animal evolution. These gelatinous creatures are clearly distinct from cnidarian medusae (i.e., jellyfish).
