Ctenophore Whole-Mount Antibody Staining
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 ...

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.

Suspected chemoreceptors in coelenterates and ctenophores
Microscopy Research and Technique, 1992AbstractChemoreceptors in coelenterates and ctenophores have not been identified with certainty. Among prospective chemoreceptive cells are the sensory nerve cells, the cnidocyst bearing cnidocytes, and the epitheliomuscular cells that are likely to be involved in feeding or aggression. Both behaviors are mediated by coordinated chemical and mechanical

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
