Definition of Placozoa in English: Placozoaplural noun ˌplakəˈzəʊəˌplakəˈzōə Zoology A minor phylum that contains a single minute marine invertebrate (Trichoplax adhaerens ), which has a flattened body with two cell layers and is the simplest known metazoan. Example sentencesExamples - Despite these attempts, relationships among Bilateria, Cnidaria, Ctenophora, Placozoa, and Porifera remain obscure.
- Of particular interest in this regard are animals in the early diverging non-bilaterian phyla Porifera, Placozoa, Cnidaria, and Ctenophora.
- Increasing evolutionary diversity for comparative genomics to early-emerging multicellular animals (e.g., Porifera, Placozoa, Cnidaria, Ctenophora) may help to decipher animal origins.
- Presently, many species are highlighted for study because of their membership in Cnidaria, Ctenophora, Placozoa, or Porifera.
- The phylum Placozoa, with its single described species Trichoplax adhaerens, is of great interest to students of metazoan evolution because of its simple composition and its resistance to secure placement within the metazoan tree.
Origin Modern Latin (plural), from Greek plakos 'flat' + zōia 'animals'.
