Bacterial community associated with Ctenophores at Helgoland Roads, German Bight
, 2013 Question Large increases in gelatinous zooplankton populations have occurred in many coastal and estuarine ecosystems worldwide because of eutrophication, climate change, and anthropogenic activities which have greatly altered the natural marine ...

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

Regulation and Regeneration in the Ctenophore Mnemiopsis leidyi
Developmental Biology, 2000 Lobate ctenophores (tentaculates) generally exhibit a remarkable ability to regenerate missing structures as adults. On the other hand, their embryos exhibit a highly mosaic behavior when cut into halves or when specific cells are ablated. These deficient embryos do not exhibit embryonic regulation, and generate incomplete adult body plans.

Ancient gene linkages support ctenophores as sister to other animals [PDF]
A central question in evolutionary biology is whether sponges or ctenophores (comb jellies) are the sister group to all other animals. These alternative phylogenetic hypotheses imply different scenarios for the evolution of complex neural systems and ...

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.

, 2022 Lobate ctenophores are often numerically dominant members of oceanic epipelagic and midwater ecosystems. Despite this, little is known about their trophic ecology.

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.

Trophic interactions of meso- and macrozooplankton and fish in the Iceland Sea as evaluated by fatty acid and stable isotope analysis [PDF]
, 2012 A trophic study was carried out in August of 2007 and 2008 on the pelagic ecosystem in the Subarctic Iceland Sea. Carbon and nitrogen stable isotopes and fatty acid biomarkers were used to study trophic linkages and the trophic ecology of the most ...
