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

Ctenophore Whole-Mount In Situ Hybridization
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

RNA Isolation from Ctenophores
RNA-seq or transcriptome analysis of individual cells and small cell populations is essential for virtually any biomedical field. Here, we examine and discuss the different methods of RNA isolation specific to ctenophores. We present a convenient, inexpensive, and reproducible protocol for RNA-seq libraries that are designed for low quantities of ...Andrea B, Kohn +2 more

Illustrated Neuroanatomy of Ctenophores: Immunohistochemistry
Ctenophores or comb jellies are representatives of an enigmatic lineage of early branching metazoans with complex tissue and organ organization. Their biology and even microanatomy are not well known for most of these fragile pelagic and deep-water species.Tigran P, Norekian, Leonid L, Moroz

Metabolism of epipelagic tropical ctenophores
Marine Biology, 1986Measurements of respiration and excretion at 25°C were made for five species of ctenophores collected during five cruises to the Bahamas (1982–1984). The mean element-specific respiration and ammonium excretion rates of freshly collected specimens of all species ranged from 4 to 16% d-1, the mean atomic O:N ratios were 10 to 16, and ammonium averaged ...

Biochemical composition of ctenophores
Journal of Experimental Marine Biology and Ecology, 1983Abstract The biochemical composition of three species of North Sea ctenophores, the beroid Beroe gracilis (Kunne), the tentaculate Pleurobrachia pileus (Fabricius) and the lobate Bolinopsis infundibulum (Muller), was analysed in terms of total fractions of protein, lipid, ninhydrin-positive substances (NFS), polysaccharides (PS), and low ...

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

Electrophysiology of Ctenophore Smooth Muscle
Unlike in the Cnidaria, where muscle cells are coupled together into an epithelium, ctenophore muscles are single, elongated, intramesogleal structures resembling vertebrate smooth muscle. Under voltage-clamp, these fibers can be separated into different classes with different sets of membrane ion channels.Meech, Robert W +2 more
