What is the mode of reproduction of medusae Of polyps?
Medusae, the adult stage of jellyfish in the life cycle of cnidarians, primarily reproduce asexually through budding in polyps and sexually as free-swimming organisms. In their polyp stage, they can produce medusae by a process called strobilation, where the polyp develops and releases multiple juvenile medusae. In contrast, medusae reproduce sexually by producing eggs and sperm, leading to the formation of a fertilized egg that develops into a free-swimming larva known as a planula. This planula eventually settles and develops into a polyp, continuing the life cycle.
How many maturing medusae are visible in a typical gonozoid?
Typically, a mature gonozoid will have one maturing medusa visible within it.
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.
How a benthocodon reproduces?
Benthocodon reproduces by releasing eggs and sperm into the water during mass spawning events. Fertilization occurs externally, and the resulting larvae develop into young medusae before settling and metamorphosing into adult benthocodon.
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.
When was Tillandsia caput-medusae created?
Tillandsia caput-medusae was created in 1880.
Why are medusae considered plankton?
The polyps may be found attached to docks or floats, while the medusae live in the plankton.
What phylum have some free drifting medusae?
Medusae are found in the phylum Cnidaria, which includes jellyfish. Some species of jellyfish have free-drifting medusae as part of their life cycle, allowing them to move through the water and feed on plankton and other small organisms.

What is a form of cnidarian that swims through water?
Medusae
How many maturing medusae are visible in a gonozoid?
7
What is the form of mudeusa look like?
a Medusa (single,medusae) is a jelly fish!
Compare the body forms of a polyp and medusa?
Polyps and medusae are two distinct body forms of cnidarians. Polyps are typically cylindrical and sessile, with a mouth and tentacles facing upward, anchored to a substrate. In contrast, medusae are free-swimming and have an umbrella-shaped, bell-like structure, with the mouth and tentacles hanging downward. This differences in morphology reflect their adaptations to different lifestyles within their life cycle, with polyps often engaging in asexual reproduction and medusae primarily involved in sexual reproduction.
Are cnidaria symmetrical?
Cnidaria have two basic body forms: swimming Medusae and sessile Polyps, and they are both radially symmetrical.
Can crystals reproduce?
No but crystal jellyfish do. Crystals reproduce by alternating between asexual benthic polyps and seasonal planktonic medusae.

How many maturing medusae are visible in a typical gonozoid?
