Hidden diversity of Ctenophora revealed by new mitochondrial COI primers and sequences [PDF]
Molecular Ecology Resources, 2021 The mitochondrial gene cytochrome‐c‐oxidase subunit 1 (COI) is useful in many taxa for phylogenetics, population genetics, metabarcoding, and rapid species identifications.

Studying Ctenophora WBR Using Mnemiopsis leidyi.
Methods in molecular biology, 2022 AbstractCtenophores, also known as comb jellies, are a clade of fragile holopelagic, carnivorous marine invertebrates, that represent one of the most ancient extant groups of multicellular animals. Ctenophores show a remarkable ability to regenerate in the adult form, being capable of replacing all body parts (i.e., whole-body regeneration) after loss ...

Extensive mitochondrial gene rearrangements in Ctenophora: insights from benthic Platyctenida
BMC Evolutionary Biology, 2018 Background Complete mitochondrial (mt) genomes have been sequenced for thousands of animals and represent a molecule of choice for many evolutionary studies. Nevertheless, some animal groups have remained under-sampled.

A speculation on the classification system of the Ctenophora [PDF]
Publications of the Seto Marine Biological Laboratory, 2014 Standing on the close relationship between the Cestida and the newly found Lobatolampea tetragona Horita, the classificational arrangement of the higher taxa of the Ctenophora is revised by plotting respective taxa at their adequate sites in the flow of evolutionary changes, suspected from the variability seen in the gastric canal system and the ...

, 2020 On April 10, 2015, three individuals of an undescribed species of ctenophore were observed moving just above the seafloor in the Arecibo Amphitheater inside the Guajataca Canyon, north-northwest of Puerto Rico at a depth of approximately 3,900 m.

Underwater Light Manipulation by the Benthic Diatom Ctenophora pulchella: From PAR Efficient Collection to UVR Screening [PDF]
Nanomaterials, 2021 Several species of diatoms, unicellular microalgae which constitute the main component of phytoplankton, are characterized by an impressive photosynthetic efficiency while presenting a noticeable tolerance versus exposure to detrimental UV radiation (UVR)

Early animal evolution: a morphologist's view [PDF]
Royal Society Open Science, 2019 Two hypotheses for the early radiation of the metazoans are vividly discussed in recent phylogenomic studies, the ‘Porifera-first’ hypothesis, which places the poriferans as the sister group of all other metazoans, and the ‘Ctenophora-first’ hypothesis ...

Journal of Water and Climate Change, 2023 Ctenophores are quick responders to coastal environmental changes and play a crucial role in marine food web dynamics. We report the environmental drivers of a ctenophore swarm (Pleurobrachia spp.) and associated ecological changes in estuarine and ...

Available data do not rule out Ctenophora as the sister group to all other Metazoa
Nature Communications, 2023 Redmond and McLysaght (RM) 1 conclude that the position of Ctenophora as sister to all other animals is unsupported. Here, we contend that this conclusion is not consistent with their analyses.

Maximum depth extensions for Hydrozoa, Tunicata and Ctenophora
Marine Biology, 2023 The observation of singleton or rare species in the deep sea is extremely valuable for gaining a census of biodiversity. At hadal depths (> 6000 m), these records provide a more complete picture of the vertical distribution of fauna.
