 | | The primary polyp produces additional polyps asexually, by budding, stolonic outgrowth, or some other process, to form a clone or a colony. |
 | | At the appropriate time, determined perhaps by size of the colony or environmental conditions, rather than or in addition to polyps, medusae are produced asexually (in Cubozoa, each polyp metamorphoses into a medusa). |
 | | A comprehensive morphological cladistic analysis by Schuchert (1993) supports the basal position of Anthozoa with the Scyphozoa and Cubozoa being more closely related to each other than to Hydrozoa. |
