What is the life cycle of a jellyfish like?
The life cycle of a jellyfish is planula - polyp - polyp budding - ephyra - medusa.
Identify the organisms that exist as either medusa or polyp form?
Jellyfish exist as either a medusa (adult free-floating) or polyp (immature attached) form during their life cycle. Another example is the Portuguese Man o' War, which also has a medusa (floating) and polyp (attached) stage.
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.
How do polyp and medusae in coelenterates alternate with each other?
Polyp is a asexual form which has a cylindrical body just like hydra whereas the medusa form is sexual form and has an umbrella shape. In case of Aurelia, the adult is sexual form. Males and females are separate and after copulation the female releases eggs which develop into a hydra like structure called ephyra larva which is called polyp form. This larva by budding produces umbrella shaped medusa forms. Thus the asexual polyp form alters with the sexual medusa form. This alternation of generations is called metagenesis.
What is metagenesis in coelentrates?
Metagenesis, also known as alternation of generations, is a reproductive phenomenon in cnidarians where individuals alternate between a polyp and medusa form throughout their life cycle. The polyp form is a sessile, cylindrical structure that reproduces asexually, while the medusa form is a free-swimming, bell-shaped structure that reproduces sexually. This alternating life cycle allows for genetic diversity and adaptation to different environmental conditions.
What are two stages of cnidarians?
Polyp and medusa are two stages in life cycle of cnidarians , polyp is hydra like and medusa is jelly fish like .
What are the 2 distinct life stages of cnidarians?
The medusa (jellyfish like) and the polyp (sea anenome like)
What is the life cycle of a jellyfish like?
The life cycle of a jellyfish is planula - polyp - polyp budding - ephyra - medusa.
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.
All three classes of cindarians have both medusa and polyp stages?
True
What is the fish baby name?
The jellyfish life cycle is; planula larva, polyp, budding polyp, ephyra, 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.
Is a moon jelly a Medusa or a polyp?
polyp
Identify the organisms that exist as either medusa or polyp form?

What is the diffence between polyp and Medusa?
polyp---sea anenome, medusa---jellyfish Phlycabs In plain English a polyp is a cylinder with tentacles at the top. The Hydra looks like a tin can with slender arms coming from the top of its body. This body form does not move and the animals are trappers. The medusa is an umbrella shaped structure with tentacles hanging down from it. The jellyfish is an example. These animals move. During the reproductive stages of the jellyfish there is a time when they take on the polyp form. Then they bud off and become medusa. Nighthawk
What are two body forms in the phylum cnidarian?
The two body forms in the phylum Cnidarian are the polyp and medusa. Polyps are usually stationary, with a cylindrical body and tentacles surrounding a central mouth. Medusas are free-swimming and have a bell-shaped body with tentacles hanging down.
What is the evolution of a polyp into a Medusa?
Within a life cycle, a cnidarian transitioning between a polyp and a medusa is not evolution. Evolution happens over many generations, not within a single one. How the two forms evolved to both take place within a single life cycle is not well understood.
