What is the advantage of the medusa over the attached polyp in the Cnidarian?
The advantage of a medusa body form over the attached polyp form in Cnidarians is increased mobility. Medusas are free-swimming and can move through the water, allowing them to spread and find food more easily. This mobility also facilitates reproduction as medusas can disperse gametes over a wider area.
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.
Which phylum has both medusa and polyp stages in its life cycle?
Cnidaria is the phylum that exhibits both medusa and polyp stages in its life cycle. Medusae are the free-swimming form, while polyps are typically attached to a substrate.
What is the relationship between a stationary polyp and free swimming medusa?
Some cnidarians have a life cyce wih an alternation of generations between asexual reproduction and sexual reproduction; while asexual reproduction provides a large increasing of (identical) individuals, sexual reproduction mantain a genetic pool variety.The generation supposed to reproduce asexually is polypoid; the generation supposed to reproduce sexually is medusoid.Tipically, medusae produce male and female gametes, which fuse together making zygotes; a zygote becames an egg from which hatches a free swimming larva called planula; the planula reaches the sea floor and developes into a polyp; the polyp then becames a strobila (segmented polyp), wich reproduces asexually by strobilation, segmenting itself and producing many ephyras, which can be released one at a time or all together at the same time; each ephyra maturates into an adult medusa, reaching the reproductive maturity.
What form of a cnidarian that attaches to a surface?

What kind of form of a cnidarian attaches to a surface?
Polyp
The free swimming form of a cnidarians called a polyp?
no
What is the free-swimming adult form of a jellyfish called?
An adult swimming cnidarian is called a medusa.
What cnidarian body form is specialized for swimming?
The cnidarian body form specialized for swimming is the medusa. Medusas are typically bell-shaped and have tentacles hanging down, allowing them to pulsate and propel themselves through the water. This form is often associated with the adult stage of jellyfish, which are well-known examples of swimming cnidarians. In contrast, the polyp body form is usually sessile and attached to a substrate.
What is a bowl shaped cnidarian that is adapted for swimming?
A bell-shaped cnidarian adapted for swimming is known as a medusa. Medusae have a jelly-like, umbrella-shaped body with tentacles hanging down and are capable of free-swimming movements in the water. They are typically the adult form of cnidarians, with the polyp form being the stationary phase in the life cycle.
What is the advantage of the medusa over the attached polyp in the Cnidarian?
The advantage of a medusa body form over the attached polyp form in Cnidarians is increased mobility. Medusas are free-swimming and can move through the water, allowing them to spread and find food more easily. This mobility also facilitates reproduction as medusas can disperse gametes over a wider area.
Is larvae considered the first form of a cnidarian?
YES. Scientists think that the first form or cnidarians was the larvae long ago. No the medusa or polyp if that is what you are thinking. Check on wikipedia if you don't believe me
What is a sessile form of a jellyfish called?
POLYP
Form of cnidarian that swims through water?
flatworm. Sometimes they're ugly, sometimes they're cute, but look up a pic!

What is the free floating body form of cnidarians?
The free floating body form of cnidarians is called a medusa. Medusae have a bell-shaped body with tentacles hanging down, and they are often seen swimming in the water. Examples include jellyfish and hydromedusae.
