This sequencing effort has produced the first set of whole-genome sequencing data on any ctenophore species, and is amongst the first wave of animal genomes to be sequenced de novo using solely next-generation sequencing technologies. Sometimes though, for convenience, scientists lump medusae and ctenophores together and call them both "jellyfish", when the scientists are trying to make a point about these two groups of unrelated organisms that are ecologically very similar and often found in the same places (see also the paragraph just above this one).

Despite long-standing experimental interest in ctenophores due to their unique biology, ecological influence and evolutionary status, previous work has largely been constrained by the periodic seasonal availability of wild-caught animals and difficulty in reliably closing the life cycle.

A number of studies on Mnemiopsis have led to a better understanding of many key biological processes, including regeneration and axial patterning, and these studies have contributed to the emergence of Mnemiopsis as an important model for evolutionary . Biol. Recent phylogenomic studies based on analyses of many genes from many taxa have produced conflicting results, leading to the realization that a complete ctenophore genome sequence would be needed to satisfactorily resolve the phylogenetic position of this phylum and its relationship to other early branching metazoans. 56, 431439 (2011). M. leidyi is probably the most-studied ctenophore genus in the world because of its great abundance next to densely populated areas in its native habitats, and because of its widespread impact on.
