The symmetry of a polyp can affect its feeding strategies and efficiency. Radially symmetrical polyps like those of cnidarians can efficiently catch prey from various directions, while bilaterally symmetrical polyps like some flatworms may have specialized structures for targeted feeding. The specific structure and arrangement of feeding tentacles or openings can depend on the polyp's symmetry and can impact its ability to efficiently capture and consume food.

What is the body symmetry of hydra?
A hydra has two body shapes. The first one is known as polyp which has tentacles and the other body form is known as 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.
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 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.

What is the body symmetry of hydra?
A hydra has two body shapes. The first one is known as polyp which has tentacles and the other body form is known as medusa.
How are radial symmetry and symmetry different?
Radial symmetry is a particular kind of symmetry in which an object takes on a similar form in any direction outward from the center (like a circle, which is the most perfect radially symmetrical form). Another form of symmetry is bilateral symmetry, meaning that is a two sided symmetry, in which a left side resembles a right side; this is the kind that human bodies have. In comparison, starfish have radial symmetry.

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 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
