Neural connectome of the ctenophore statocyst. [PDF]
ElifeAbstract Ctenophores possess a unique gravity receptor (statocyst) in their aboral organ formed by four clusters of ciliated balancer cells that collectively support a statolith. During reorientation, differential loads on the balancer cilia lead to altered beating of the ciliated comb rows to elicit turns.

Omnidirectional propulsion in a metachronal swimmer. [PDF]
PLoS Computational Biology, 2023 Aquatic organisms often employ maneuverable and agile swimming behavior to escape from predators, find prey, or navigate through complex environments. Many of these organisms use metachronally coordinated appendages to execute complex maneuvers. However,

The hidden biology of sponges and ctenophores [PDF]
Trends in Ecology and Evolution, 2015 Animal evolution is often presented as a march toward complexity, with different living animal groups each representing grades of organization that arose through the progressive acquisition of complex traits. There are now many reasons to reject this classical hypothesis.

Nitric oxide signaling in ctenophores
Frontiers in Neuroscience, 2023 Nitric oxide (NO) is one of the most ancient and versatile signal molecules across all domains of life. NO signaling might also play an essential role in the origin of animal organization.

Recording cilia activity in ctenophores: effects of nitric oxide and low molecular weight transmitters [PDF]
Frontiers in Neuroscience, 2023 Cilia are the major effectors in Ctenophores, but very little is known about their transmitter control and integration. Here, we present a simple protocol to monitor and quantify cilia activity and provide evidence for polysynaptic control of cilia ...

Jellyfish and Ctenophores in Limfjorden (Denmark)—Mini-Review, with Recent New Observations
Journal of Marine Science and Engineering, 2014 Limfjorden is a major Danish water system that connects the North Sea via Thyborøn Kanal in the west and to the Kattegat in the east. Limfjorden is heavily eutrophicated and certain areas suffer from oxygen depletion each summer.

Sponges, ctenophores, and the statistical significance of syntenies. [PDF]
Mol Biol EvolShared fusions between ancestral chromosomal linkage groups have previously been used to support phylogenetic groupings, notably sponges with cnidarians and bilaterians to the exclusion of ctenophores, rendering ctenophores the sister group to all other animals.

Reproductive success of inbred strain MV31 of the ctenophore Mnemiopsis leidyi in a self-sustaining inland laboratory culture system [PDF]
HeliyonCtenophores are an attractive phylogenetic lineage for studying animal evolution due to their early divergence from other metazoans. Among Ctenophora, Mnemiopsis leidyi is a model system for developmental, cellular, molecular genetic, and evolutionary ...

Molecular diversity of benthic ctenophores (Coeloplanidae) [PDF]
Scientific Reports, 2017 Coeloplanidae, the largest family of benthic ctenophores, comprises 33 species, all described based on traditional morphological characteristics, such as coloration, length, and number of aboral papillae, which are highly variable and can be affected by ...

Morphological and dietary changes encoded in the genome of Beroe ovata, a ctenophore-eating ctenophore. [PDF]
NAR Genom BioinformAbstract As the sister group to all other animals, ctenophores (comb jellies) are important for understanding the emergence and diversification of numerous animal traits. Efforts to explore the evolutionary processes that promoted diversification within Ctenophora are hindered by undersampling genomic diversity within this clade.
