There are tentacles with a different shape than polyps, photoreceptors, and gravity-detecting osteocytes that surround the bell. Corals have separate sexes, some corals have male organs while others have female organs in the same ways some of the corals are hermaphrodites in nature i.e they have both male and female organs on the same body. Medusa is formed by a bell capable of muscular contractions which enables the medusa to swim. The best-known member of the Hydrozoa is the hydra, a freshwater species. polyps are an View the full answer Transcribed image text: Cnidarian Questions 1. But, the planula larva may transform directly into the medusa in a few Cnidarians. A polyp is one of the forms found in the members of Cnidarians with a tubular body and sessile lifestyle, A medusa is one of the forms found in the members of Cnidarians with a saucer-shaped body and free-floating lifestyle, Polyps are non-motile, sessile, or fixed zooids, Medusae are motile or free-swimming organisms, They appear more or less cylindrical shape with a long stalk, They appear umbrella-like with a reduced stalk, Polyps are attached to the rocks underwater, They are adapted for a sessile or sedentary life, Simple (body contains a cylindrical trunk and a flattened oral disc), Complex (body comprises a central bell and numerous marginal tentacles), Medusa of the class Hydrozoa comprises a tube-like manubrium that hangs down from the bell, Polyp has a single circular and terminal mouth, Medusa has a four-sided mouth present downwards or at the lower end of the hanging manubrium, Tentacles surround the mouth as a ring of tentacles, Tentacles surround a central bell and hang downwards at the margin, It is simple without radial and circular canals, It has four radial canals and one circular canal, Absent (Polyps are unable to move on their own), Present (Medusae are able to move on their own), Medusae have eight sense organs called statocysts and photoreceptors, The majority of polyps lack sex organs or gonads, but a few may produce gonads, Medusa participates in sexual reproduction and distribution of species, They mainly reproduce asexually by budding or sexually by spawning following the release of pheromones, They exclusively reproduce via sexual reproduction by releasing gametes underwater. Medusa is a life cycle stage of the species who belongs to cnidaria phylum. Mode of reproduction in medusa is sexual, but their development varies within the class of the cnidaria phylum as in case of hydrozoa class new members are formed by budding. Medusa is the reproductive stage and polyp is the asexual stage of Hydrozoans. 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. Both sessile and swimming members can be found in Hydrozoa. Polyps are seen in adult corals and sea anemones. 4. Any freshwater or marine coelenterate of the class Hydrozoa, including free-swimming or attached types, as the hydra, in which one developmental stage, either the polyp or medusa, is absent, and colonial types, as the Portuguese man-of-war, in which both medusa and polyp stages are present in a single colony. They reproduce only by sexual mode of reproduction. Polyp species are tabular in their body shape while medusa are not in the tabular in body shape. Several types of tentacles like photoreceptors, gravity-sensing osteocytes surround the bell.
