What are the three classes of cnidarians and how do they differ from each other?
What will be an ideal response?
Class Hydrozoa includes colonial cnidarians that posses both polyp and medusoid stages during their development. Hydrozoans include both sessile and planktonic representatives. Members of the class Scyphozoa include solitary jellyfish that usually only posses a medusoid stage that is planktonic rather than sessile. Class Anthozoa contains the anemones and coral polyps. Only the polyp stage is present in this group, which contains sessile animals.
