Some Cnidarians alternate between polyp and medusa forms (Metagenesis), with polyps asexually producing medusae and medusae sexually producing polyps, as seen in Obelia.
Cnidarians with both polyp and medusa forms exhibit alternation of generation (Metagenesis), where polyps produce medusae asexually and medusae produce polyps sexually (e.g., Obelia).
| Text | Those cnidarians which exist in both forms exhibit alternation of generation (Metagenesis), i.e., polyps produce medusae asexually and medusae form the polyps sexually (e.g., Obelia). |
