Medusa is created by the transformation of the polyp in other cnidarian classes, such as Cubozoa or Rhizostomae. Morphologically, a medusa is formed by a bell capable of muscular contractions which enables the medusa to swim. Among these external receptor photoreceptors and statocytes act as a sense organs present only in medusa and lacking in the polyp.
