A review of cnidarians and ctenophores feeding on competitors in the plankton
Hydrobiologia, 1991 Predation among pelagic cnidarians and ctenophores is reviewed. The diets of semaeostome scyphomedusae and hydromedusae commonly include other gelatinous zooplanktivores.

Cilia and the life of ctenophores
Invertebrate Biology, 2014AbstractCtenophores, or comb jellies, are a distinct phylum of marine zooplankton with eight meridional rows of giant locomotory comb plates. Comb plates are the largest ciliary structures known, and provide unique experimental advantages for investigating the biology of cilia.

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 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 ...

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.
