Question

Anthozoans, such as corals and sea anemones, only exhibit the polyp stage in their life cycle. Other cnidarians, such as hydrozoans, scyphozoans, and cubozoans, exhibit both the polyp and medusa stages in their life cycle. Bryozoans are a separate phylum of aquatic invertebrates, not cnidarians.
