Morphologically, cnidarians categorize as medusae or polyps. Polyps are cylindrical and medusae are the circular convex, similar to an umbrella. Both shapes contain tentacles.

In common polyps are sessile however certain species, such as hydra, can move by modifying contact points on the substrate and executing somersaults. Medusae can shift expelling water jets by contraction of body. Various cnidarians vary medusoid and polypoid forms in their life cycle.
