Sometimes it contains skeletal elements which are formed by the cells migrated to form the ectoderm. While polyp lack the presence of sense organs, medusa have photoreceptors and gravity-sensing statocytes. The lower end of the polyp typically is adapted for attachment to a surface. Medusa are more evolved, being mobile, presenting sense organs such as the photoreceptors and the statocytes, and reproducing sexually which promotes genetic diversity. The fusion of sperm and egg turns into a zygote that later develops into Planula larvae. Polyps appear more or less cylindrical, whereas medusae appear umbrella-shaped. Among these external receptor photoreceptors and statocytes act as a sense organs present only in medusa and lacking in the polyp.
