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. The invasive ctenophore Mnemiopsis leidyi, which comes from North America's east coast, was observed in Danish waters for the first time in 2007 and has apparently come to stay, as it has no effective enemies.

MicroRNAs play a vital role in the regulation of gene expression in all non-ctenophore animals investigated thus far except for Trichoplax adhaerens, one of three known members of the phylum Placozoa.
