The polyp is solitary and sessile and can be isolated, as in a sea anemone, or a coral. At a given time following the secretion of pheromones, corals release a big number of sexual cells in the water. Polyp produces the jellyfish-shaped medusae asexually, and medusae produce the sperm and eggs. But, hydrozoans, scyphozoans, and cubozoans alternate generations between polypoid and medusoid body forms. Polyp can reproduce asexually by budding, or sexually by spawning following the release of pheromones. He holds a BSc in Natural Sciences and Post Graduate Diploma in Environmental Science.

The mesoglea varies from a very thin layer to a fair thickness. Also, another advantage of polymers; is that the melting temperature of plastics is low generally, which provides low processing temperatures for polymers. In the case of Hydrozoa, their mouth is present at the end of a tube hanging down from the bell, which is known as manubrium. Causes of Polymorphism: ADVERTISEMENTS: Polymorphism is due to the division of labour, diversification of forms and specialization. Both polyps and medusa are life stages of different organisms.
