ParaHoxozoa (or Parahoxozoa) is a clade of animals that consists of Bilateria, Placozoa, and Cnidaria. The relationship of this clade relative to the two other animal lineages Ctenophora and Porifera is debated.

The nematodes ( / ˈnɛmətoʊdz / NEM-ə-tohdz or NEEM-; Greek: Νηματώδη; Latin: Nematoda ), roundworms or eelworms constitute the phylum Nematoda. [3] [4] They are a diverse animal phylum inhabiting a broad range of environments. Most species are free-living, feeding on microorganisms, but there are many that are parasitic. [3]
The basal eumetazoan clades are the Ctenophora and the ParaHoxozoa. Placozoa is now also seen as a eumetazoan in the ParaHoxozoa. The competing hypothesis is the Myriazoa clade.
The ParaHox gene cluster has been proposed to be a paralogue, or evolutionary sister, of the Hox gene cluster; [1] the two gene clusters being descendent from a segmental duplication early in animal evolution, preceding the divergence of cnidarians and bilaterian animals. [5] It has been suggested that an ancient role of the ParaHox gene ...
Clades. Placozoa. Cnidaria. Triploblasts / Bilateria. ParaHoxozoa is a proposed group within taxonomy. It would be a clade, above phylum but below a kingdom. It would include the Bilateria, the Placozoa and the Cnidarians. [1] [2] [3] [4] [5] [6] [7]
Parazoa ( Parazoa, gr. Παρα-, para, "next to", and ζωα, zoa, "animals") are a taxon with sub-kingdom category that is located at the base of the phylogenetic tree of the animal kingdom in opposition to the sub-kingdom Eumetazoa; they group together the most primitive forms, characterized by not having proper tissues or that, in any case, these t...
