Planulozoa is a

Porifera (sponges).[10][11][12] Although this clade was sometimes used to specify a clade of Cnidaria and Bilateria to the exclusion of Placozoa (against the original intention of its proposal), this is no longer favoured due to recent data indicating a sister group relationship between Cnidaria and Placozoa.[13]

The phylogenetic tree indicates approximately how many millions of years ago (mya) the lineages split. Here, Planulozoa is shown sans Placozoa.[14][15][16]

Planulozoa are associated with the emergence of the Zoc and ZF-NC gene domains.[17]
