Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.Abstract Gelatinous zooplankton (GZ) have been proposed as a potentially important but largely overlooked contributor to the biological carbon pump. However, estimates of GZ‐derived carbon transfer efficiency to the ocean floor reflect uncertainties in key parameters that govern carbon export, leading to contrasting interpretations of the role of GZ in

Evolution: Ctenophore Genomes and the Origin of Neurons
, 2014 SummaryRecent sequencing of ctenophore genomes opens a new era in the study of this unique and phylogenetically distant group. The presence of neurodevelopmental genes, pre- and postsynaptic modules, and transmitter molecules is consistent with a single ...

A collection of recent ctenophore sightings from the Maltese Islands [PDF]
, 2011 The only ctenophore reports from Maltese coastal waters ever published date back to over 40 years ago, with only two comb jelly species being previously recorded from such waters. A collection of recent ctenophore sightings from Maltese coastal waters,

Establishing and maintaining primary cell cultures derived from the ctenophore Mnemiopsis leidyi
, 2017 We have developed an efficient method for the preparation and maintenance of primary cell cultures isolated from adult , a lobate ctenophore. Our primary cell cultures are derived from tissue explants or enzymatically dissociated cells, and maintained in

Ctenophores and the evolutionary origin(s) of neurons
Trends in Neurosciences, 2022 Ctenophores (commonly known as comb jellies) are among the earliest branching extant lineages of the animal kingdom. Here, I present a brief overview of the ctenophore nervous system, discussing its cellular architecture and molecular composition, as well as insights it offers into the early evolution of neurons and chemical neurotransmission.

PLoS ONE, 2017 Photoproteins are responsible for light emission in a variety of marine ctenophores and coelenterates. The mechanism of light emission in both families occurs via the same reaction.

Convergent evolution of neural systems in ctenophores [PDF]
Journal of Experimental Biology, 2015 Neurons are defined as polarized secretory cells specializing in directional propagation of electrical signals leading to the release of extracellular messengers – features that enable them to transmit information, primarily chemical in nature, beyond their immediate neighbors without affecting all intervening cells en route.

, 2021 Active hydromedusan and ctenophore Ca2+-regulated photoproteins form complexes consisting of apoprotein and strongly non-covalently bound 2-hydroperoxycoelenterazine (an oxygenated intermediate of coelenterazine).
