| The life cycles of the hydrozoans P. carnea and Hydractinia echinata and a representative anthozoan. |
| Examples of other colonies are anthozoan soft corals and most reef-forming hard corals. |
| One of the basic issues regarding the evolution of anthozoan colors that can be addressed at the present state of knowledge is the basis of intraspecific color variation. |
| It is not homologous with the bilaterality of body plans characteristic of anthozoan groups. |
| The chaetetids compose a small group of organisms that was most often presumed to be among the anthozoan corals, more specifically allied to the Tabulata. |
| The origin of such symmetry is not related to the basic anthozoan body plan. |
