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?
In the life cycle of cnidarians like jellyfish (coelenterates), polyps reproduce asexually by budding to produce medusae. The medusae then reproduce sexually to form new polyps where the cycle continues. This alternation of generations allows for both sexual and asexual reproduction within the cnidarian life cycle.
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.
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.
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

Are cnidaria symmetrical?

What has the author Edward T Browne written?
Edward T. Browne has written: 'Medusae' -- subject(s): Cnidaria, Jellyfishes
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?
Typically, a mature gonozoid will have one maturing medusa visible within it.
What are cnidae?
Cnidae (singular: cnida) are tiny capsules which contains a coiled tubule and venom that causes stings when a human stung by a Jellyfish Medusae.
What is an acalephan?
