Ctenophores: an evolutionary-developmental perspective
Current Opinion in Genetics & Development, 2016Ctenophores are non-bilaterian metazoans of uncertain phylogenetic position, some recent studies placing them as sister-group to all other animals whereas others suggest this placement is artefactual and ctenophores are more closely allied with cnidarians and bilaterians, with which they share nerve cells, muscles and gut.

This chapter deals with the total luminescent fauna of the phylum, Ctenophora,; the emission maxima in observed species of ctenophores, the description of luminescent species of ctenophores, and their mechanism of bioluminescence.

Ctenophores constitute a small phylum of approximatly 100 species. All species are marine and most of them are large planktonic forms moving with 8 rows of beating ciliated comb plates (ctenes). The animals have a simple body plan with biradial symmetry defined by the position of the tentacles (tentacular plane) and the stomodeum (sagittal or stomodeal

Transactions of the American Fisheries Society, 1983
Abstract Ctenophores constituted most of the stomach contents of 50 chum salmon Oncorhynchus keta and one chinook salmon O. tshawytscha caught in British Columbia waters during summer 1981. Ctenophore remains are difficult to identify, and such food may be more important to Pacific salmon than hitherto realized. Received February 10, 1983 Accepted June

Ctenophore Tissue Preparation and Extraction of DNA
Cold Spring Harbor Protocols, 2008INTRODUCTIONCtenophores, or comb jellies, are a group of marine animals whose unique biological features and phylogenetic placement make them a key taxon for understanding animal evolution. Some characteristics are present in nearly all ctenophores, including biradial symmetry, comb rows composed of linked cilia, an apical sensory organ, and two ...

DNA Methylation in Ctenophores
Epigenomic regulation and dynamic DNA methylation, in particular, are widespread mechanisms orchestrating the genome operation across time and species. Whole-genome bisulfite sequencing (WGBS) is currently the only method for unbiasedly capturing the presence of 5-methylcytosine (5-mC) DNA methylation patterns across an entire genome with single ...Emily C, Dabe +2 more

The onset of regenerative properties in ctenophores
Current Opinion in Genetics & Development, 2016Ctenophores are a clade of animals that branch off at the base of the animal tree. They have a unique and delicate body plan, and distinct pattern forming mechanisms at different life history stages. They have a stereotyped embryonic cell lineage and are highly 'mosaic' as embryos, but most have amazing capacity to regenerate as adults.

Recording Cilia Activity in Ctenophores
Pelagic ctenophores swim in the water with the help of eight rows of long fused cilia. Their entire behavioral repertoire is dependent to a large degree on coordinated cilia activity. Therefore, recording cilia beating is paramount to understanding and registering the behavioral responses and investigating its neural and hormonal control.Tigran P, Norekian, Leonid L, Moroz
