Sea Challengers and the Monterey Bay Aquarium, Monterey, It might have occurred naturally by drifting individuals, or with ballast water of ships, either from its natural range or from the Black Sea, via the Mediterranean and eastern Atlantic. 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. Many aquariums would like to exhibit a ctenophore, since public interest Phylogenet. When food becomes available, the animal Visualization: J.S.P.
