Saucer-shaped, an umbrella-like structure containing reduced stalk. Polyp: It is concerned with feeding, protection and asexual reproduction. Medusa is created by the transformation of the polyp in other cnidarian classes, such as Cubozoa or Rhizostomae. When we can remove repetition from our routines, then we can focus on the creative endeavors that technology cannot duplicate. It represents the asexual stage. The difference between polyp and medusa is that the ability to locomote, polyps are stagnant animals with no ability to freely swim whereas medusae class organisms can freely swim in the seawater. cnidarian body form.

Also, another advantage of polymers; is that the melting temperature of plastics is low generally, which provides low processing temperatures for polymers. The medusoid body is bell- or umbrella-shaped. These two structures are found in invertebrates phylum Cnidaria i.e Coelenterates. But, hydrozoans, scyphozoans, and cubozoans alternate generations between polypoid and medusoid body forms. Jellyfish is considered as the oldest multi-organ animal, which roamed the sea for at least 500 million years. The cavity then opens, tentacles grow, and the tissue that connects the medusa to the parent polyp constricts, allowing the freshly born medusa to emerge.

What is the difference between Polyp and Medusa. In contrast, medusa are a more evolved form of cnidarians, being mobile, reproducing sexually which promotes genetic diversity, and presenting photoreceptors and statocytes as sense organs. The key difference between polyp and medusa is that polyp is a fixed, cylindrical structure, representing the asexual stage and medusa is a free swimming, umbrella-like structure, representing the sexual stage. Their mouth is present at the opposite end and is surrounded with tentacles forming the head part.
