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. Zebrafish larvae (Danio rerio) that have been pre-washed with ASW are delivered directly to the tentacle lined feeding grooves via plastic pipette where they become ensnared in adhesive material produced by colloblast cells lining the tentilla.

Many aquariums would like to exhibit a ctenophore, since public interest cycle in the plankton, so they are considered to be "holoplanktonic".
