Many species of the phylum Cnidaria have two separate life cycle stages: polyp and medusa. 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. In contrast, the polyp population predominates in hydrozoans and Cubozoans. They are mostly free-swimming in nature. Simple and lacks radial and circular canals. For example, the hydra has only a polyp stage, for example, whereas most hydrozoans have a biphasic (two-stage) life cycle that alternates between a sedentary polyp stage and a mobile, bell-shaped medusa stage. 1) Advantage of Medusas Stage - the Cnidarians move with the tentacles in water and also gets the nutrition from capturing prey - helps in localization in difficult Conditions The advantage of being Polyp -especially in the ocean , i.e. Cnidarians have stinging cells in their Despite the advantages of enrolling in Original Medicare, the program also has disadvantages, which include: Out-of-pocket costs Even after meeting your deductibles for premium-free Part A ($1,556 per benefit period in 2022) and Medicare Part B ($233 per year in 2022), the out-of-pocket costs associated with Medicare can add up rather quickly . jellyfish. 3 advantages flatworms have over cnidarians. 10 Differences between Kwashiorkor and Marasmus (Kwashiorkor vs Marasmus), Differences between Megabyte and Mebibyte (MB vs MiB), Difference between Global and Local Sequence Alignment, 10 Differences between RAM and ROM in Tabular form.

Polyp is a sessile life cycle stage of species who belong to phylum cnidaria. The majority of members belonging to the phylum Cnidaria exhibit polymorphism. Medusa are free swimming, reproduce sexually with cross-fertilization increasing genetic diversity, and present a more complex morphology than the polyp form. Polyp present a tubular shape with the mouth facing the water upwards,while medusa present a bell shape with the mouth facing the water downwards. Their month and tentacles face the direction of water. They are free-swimming animals that float along water currents by rhythmic muscular contractions of the bell.
