| The origin of such symmetry is not related to the basic anthozoan body plan. |
|
| This complicated bilayered structure is typical of anthozoan late planula larvae. |
|
| It is not homologous with the bilaterality of body plans characteristic of anthozoan groups. |

|
| Anthozoans are readily available on coral reefs therefore it's not surprising that anthozoan tissue is their main diet. |
|
| 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. |
|
| When Wotton in 1552 gave to anthozoan corals and gorgonians, and hydrozoans the name Zoophyte, it was because of their morphological similarity to higher plants. |
|
| 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 has been proposed that the most recent common ancestor between cnidarians and bilaterians would have been morphologically similar to a pennatulacean anthozoan. |
|
| An anthozoan coral polyp, which resembles a sea anemone, can nearly completely retract into the calcareous cup it secrets around itself. |
|
| Examples of other colonies are anthozoan soft corals and most reef-forming hard corals. |
|
| The last major category of cnidarian skeletons, formed by the anthozoan subclass Alcyonaria and the order Antipatharia, are internal. |
|
| Additional evidence for a role for estrogen in anthozoan reproduction comes from measurements of estrogen release into seawater prior to or during spawning events. |
|
| The main anthozoan subclass, which includes the corals, is the Zoantharia. |
|
| Anthozoan cnidarians lack the medusoid lifestage found in other Cnidaria. |
