From a phylogenetic standpoint, the relationship of ctenophores to other animals has been a source of long-standing debate. 42, 255267 (1973). Most feed using a pair of highly extensible, usually branched, These protocols have been successfully applied to maintain long-term multigenerational cultures of several species of pelagic ctenophores, and can be utilized by laboratories lacking easy access to the ocean.

Most of these homeobox genes from the ctenophore Mnemiopsis leidyi begin expression at gastrulation, and their expression patterns suggest a possible role in patterning of the tentacle apparati and pharynx. The species overwinters in the deep waters where the temperature does not drop below 4C (39F); the fact that the Baltic is heavily stratified, with the waters above and below the halocline mixing little, is believed to aid its survival.
