The ctenophore species Mnemiopsis leidyi is known to have a large set of voltage-gated K+ channels, but little about the functional diversity these channels or their evolutionary history in other species. Here, we searched genomes two additional species, Beroe ovata and Hormiphora californensis, for functionally expressed subset M. channels. We found that last common ancestor three disparate lineages probably had at least 33 Two genes belong EAG family, remaining 31 Shaker family form single clade within animal/choanoflagellate phylogeny. additionally evidence 10 transcriptome early branching lineage Euplokamis dunlapae, suggesting diversification was already underway evolution. 16 Shakers they encode diverse array conductances with orthologs many classic subtypes cnidarians bilaterians. Analysis data show are wide variety cell types, including neurons, muscle, comb cells, colloblasts. Ctenophores therefore appear independently evolved much channel shared between
