Diagnosis Cnidaria with mostly epidermal gonads. Original life cycle includes a polyp and a medusa stage. The medusa stage develops the gonads. Polyps always without internal septae and pharynx, mostly radially symmetric. Medusae produced by budding from polyp stage, if such a stage is present. Medusa nearly always with a velum, without rhopalia. The original life cycle has been modified extensively: the medusa stage is often reduced to a mere appendage of the polyp stage, rarely completely reduced. In some orders the polyp stage is strongly or completely reduced. Polyp stages form often colonies of macroscopic size. Integrated colonies including polypoid and medusoid structures can also form complex colonies, giving them it the appearance of an individual organism. [details]
