Planulozoa is a proposed basal ParaHoxozoa clade, conventionally as sister of the Placozoa. It contains the Cnidaria (sea anemones and jellyfish) and the Bilateria (all the more complex animals including flatworms, insects and vertebrates). The Placozoa may be a sister of Cnidaria[1][2][3][4] or more conventionally of Planulozoa.[5] The clade excludes basal animals such as the Ctenophora (comb jellies),[6][7][8] and Porifera (sponges).[9][10][11]
The phylogenetic tree indicates approximately how many millions of years ago (mya) the lineages split.[12][13][14]
