Cambrian Sessile, Suspension Feeding Stem-Group Ctenophores and Evolution of the Comb Jelly Body Plan [PDF]

open access: bronzeCurrent 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 ...

Invasion of Danish and Adjacent Waters by the Comb Jelly Mnemiopsis leidyi—10 Years After [PDF]

open access: diamondOpen 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).

Mechanisms behind the metabolic flexibility of an invasive comb jelly

open access: closedJournal 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

High throughput SNP chip as cost effective new monitoring tool for assessing invasion dynamics in the comb jelly Mnemiopsis leidyi [PDF]

open access: goldFrontiers in Marine Science, 2022
High throughput low-density SNP arrays provide a cost-effective solution for population genetic studies and monitoring of genetic diversity as well as population structure commonly implemented in real time stock assessment of commercially important fish ...

A sticky thicket of glue cells: A comparative morphometric analysis of colloblasts in 20 species of comb jelly (phylum Ctenophora)

open access: goldCiencias Marinas, 2020
Ctenophores in the class Tentaculata are distinct from Cnidarians in that they use sticky, not stinging, tentacles to capture and subdue their prey.

Out of sight: aggregations of epizoic comb jellies underneath mushroom corals [PDF]

open access: bronzeCoral Reefs, 2013
Over two-thirds of all known species of comb jellies (Ctenophora) are planktonic, whereas the remainder (order Platyctenida) is composed of benthic species. Many of these are epizoic, some of which (Coeloplana spp.) are on octocorals (Matsumoto and Gowlett-Holmes 1996; Song and Hwang 2010), but none have been reported in association with scleractinians

Reproductive condition and ovarian atresia in the common kilka (Clupeonella cultriventris) from the Caspian Sea years after a dramatic outbreak of the comb jelly fish (Mnemiopsis leidyi)

open access: diamondScientia Marina, 2013
To assess the reproductive condition of the common kilka, Clupeonella cultriventris, the somatic condition and reproductive characteristics were studied by histological analysis.

Study of ecological relationships among biological groups of phytoplankton, zooplankton, Jelly comb and macrobenthos at the southeast of the Caspian Sea (Mazandaran-Goharbaran)

open access: green‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2018
This study was carried out at the southeast of the Caspian Sea on the shores of the Goharbaran region during 2013-2014. Sampling was repeated monthly in eight stations.

Genomic data do not support comb jellies as the sister group to all other animals [PDF]

open access: bronzeProceedings of the National Academy of Sciences, 2015
SignificanceClarifying the phylogeny of animals is fundamental to understanding their evolution. Traditionally, sponges have been considered the sister group of all other extant animals, but recent genomic studies have suggested comb jellies occupy that position instead.
