| The phylum Cnidaria comprises approximately 10,000 species of tentacle-bearing aquatic animals. |
|
| The Phylum Cnidaria includes such diverse forms as jellyfish, hydra, sea anemones, and corals. |
|
| Despite these attempts, relationships among Bilateria, Cnidaria, Ctenophora, Placozoa, and Porifera remain obscure. |
|
| In any case, there is molecular evidence to suggest that the Anthozoa are the earliest branch of the phylum Cnidaria. |
|
| The Cnidaria and Ctenophora are grouped together by some workers as the Coelenterata. |
|
| Of particular interest in this regard are animals in the early diverging non-bilaterian phyla Porifera, Placozoa, Cnidaria, and Ctenophora. |
|
| Presently, many species are highlighted for study because of their membership in Cnidaria, Ctenophora, Placozoa, or Porifera. |
|
| Members of the phylum Cnidaria, these animals have capsule-shaped cells with a trapdoor-like lid, containing a stinging nematocyst. |
|
| This pattern is typical of most Porifera, Cnidaria, Bryozoa with coronate larvae, colonial Ascidiacea and many polychaetes. |
|
| Jellyfish belong to one of the oldest extant animal phyla, the Cnidaria. |
|
| Pelagic species were from the Chaetognatha, Cnidaria, Crustacea, Ctenophora, and Mollusca, and benthic species were from the Chordata, Crustacea, Mollusca, and Echinodermata. |
|
| Porifera and Cnidaria are radially symmetrical, not bilaterian, and not triploblastic. |
|
| Sketch the Obelia Cnidaria medusa Obelia Medusae slide and label the bell, Deerhorn coral skeleton mouth, and tentacles. |
|
| There is strong evidence for species of Cnidaria and Porifera existing in the Ediacaran and possible members of Porifera even before that during the Cryogenian. |
|
| Ctenophores have been purported to be the sister lineage to the Bilateria, sister to the Cnidaria, sister to Cnidaria, Placozoa and Bilateria, and sister to all other animals. |
