RELATIONS BETWEEN NERVES AND CILIA IN CTENOPHORES [PDF]

American Zoologist, 1965
Waves of excitation, visible as ciliary waves, pass along the elongated cells of the ciliated grooves to the comb plates. The frequency of waves is controlled by the loading of the statolith on the balancer cilia, which stand at the head of the grooves. They are primitive mechanoreceptor cilia.

Digenean metacercaria (Trematoda, Digenea, Lepocreadiidae) parasitizing "coelenterates" (Cnidaria, Scyphozoa and Ctenophora) from Southeastern Brazil

Brazilian Journal of Oceanography, 2005
Metacercaria specimens of the genus Opechona (Trematoda: Digenea: Lepocreadiidae) are described parasitizing "coelenterates" (scyphomedusae and ctenophores) from Southeastern Brazil (São Paulo state).

Lim homeobox genes in the Ctenophore Mnemiopsis leidyi: the evolution of neural cell type specification

EvoDevo, 2012
Background Nervous systems are thought to be important to the evolutionary success and diversification of metazoans, yet little is known about the origin of simple nervous systems at the base of the animal tree.

Jellyfish and Ctenophores Around Gotland in the Baltic Sea—Local Data Contributing to Global Assessments

Journal of Marine Science and Engineering
In this study, we investigate the diversity and spatiotemporal distribution of gelatinous zooplankton (GZ) in the central Baltic Sea (coastal waters of Gotland and adjacent Eastern and Western Gotland Basins), a region characterised by low salinity and ...

Detecting the invisible through DNA metabarcoding: The role of gelatinous taxa in the diet of two demersal Antarctic key stone fish species (Notothenioidei)

Environmental DNA
Gelatinous zooplankton (GZP), i.e., ctenophores, cnidarian medusae, chaetognaths, appendicularians and salps, are considered climate change winners. This becomes particularly obvious in the Southern Ocean, which has undergone a significant shift from a ...

Extracellular DNA traps in a ctenophore demonstrate immune cell behaviors in a non-bilaterian

Nature Communications
The formation of extracellular DNA traps (ETosis) is a first response mechanism by specific immune cells following exposure to microbes. Initially characterized in vertebrate neutrophils, cells capable of ETosis have been discovered recently in diverse ...
