What are the two body forms of cnidarians?
The two body forms of cnidarians are the polyp and the medusa. Polyps are typically sessile, tube-shaped organisms attached to a substrate, while medusae are free-swimming, umbrella-shaped organisms.
Are polyp is vertebrates or invertebrates?
Polyp is invertebrate .
What do the two body forms of cnidarians look like?
Cnidarians have two main body forms: the medusa form, which is free-swimming and umbrella-shaped, and the polyp form, which is stationary and tube-shaped. Medusae have tentacles around the edge and a central mouth, while polyps have a columnar body with tentacles surrounding a central mouth.

What are a medusa shape and a polyp shape look like?

What major difference distinguishes the life cycles of hydrozoans and anthozoans?
One major difference is that hydrozoans typically exhibit both medusa and polyp stages in their life cycle, while anthozoans only have a polyp form. Hydrozoans can undergo alternation of generations, switching between medusa and polyp forms, while anthozoans remain primarily as polyps throughout their life cycle.
Is star coral a polyp or a Medusa?

What are the two phases if coelenterates?
The two phases in the life cycle of coelenterates are the polyp stage and the medusa stage. The polyp stage is characterized by a tubular body with tentacles facing upwards, while the medusa stage is characterized by a bell-shaped body with tentacles facing downwards. These two stages alternate in the life cycle of coelenterates.
What organisms that exist as either a medusa or polyp form.?
Organisms that exist in both medusa and polyp forms belong to the phylum Cnidaria, which includes jellyfish, corals, and sea anemones. In this life cycle, the medusa form is typically free-swimming and reproduces sexually, while the polyp form is usually sessile and can reproduce asexually. Examples include the common jellyfish (Aurelia aurita) and various coral species, which exhibit these two forms at different stages of their life cycle.
How do polyps differ from Medusas?
In organisms that exhibit both forms, the polyp is the asexual stage and the Medusa the sexual stage. In such organisms the polyp, by budding, gives rise to Medusa, which either detach themselves and swim away or remain permanently attached to the polyp. The Medusa then produce new polyps by sexual reproduction. A Medusa produces eggs or sperm, which are usually shed into the water; when an egg is fertilized, it develops into a swimming larva, which eventually settles and grows into a polyp. In addition to this elaborate means of reproduction, the polyp can form new polyps by budding. In some groups of coelenterates either the polyp or the Medusa has become highly developed, with the reduction or complete loss of the other form. Where only the Medusa occurs, as in many jellyfish, the larva never settles, and grows directly into a Medusa. Where only the polyp exists, as in the hydra and the sea anemone, the organism has the ability to produce new polyps sexually, as well as by budding.
What shapes do cnidarains come in?
a Medusa or a Polyp.
