Jellyfish are amazing creatures that come in two different forms: medusa and polyps. Polyps are roughly cylindrical in shape and elongated at the axis of the vase-shaped body. They can reproduce asexually by budding, while medusae spawn eggs and sperm to reproduce sexually.
So, how are jellyfish born?
Jellyfish are born from polyps, which are small, tubular structures that attach to surfaces in the water. The polyps reproduce asexually by budding, and the new jellyfish then break away from the parent polyp and begin to grow and develop into medusae. Medusae are the free-swimming form of jellyfish, and they reproduce sexually by releasing eggs and sperm into the water. The eggs are fertilized by the sperm and develop into new jellyfish, which then begin the cycle anew.
Let’s dig into it and see what’s inside.
How Does The Jellyfish Life Cycle Work?
Jellyfish take on two different body forms throughout their life cycle – medusa and polyps. The medusa is the sexual phase, during which jellyfish reproduce. The polyp phase is the asexual phase, during which jellyfish grow and mature.
Jellyfish reproduce by releasing eggs and sperm into the water. The eggs are fertilized by the sperm and then develop into larvae. The larvae settle on the bottom of the ocean and develop into polyps. The polyps reproduce asexually by budding off new polyps. Eventually, the polyps develop into medusa and the cycle starts over again.
The immortal jellyfish, Turritopsis dohrnii, is able to cheat death by reverting back to its polyp form when conditions are unfavorable. This allows the jellyfish to essentially start its life over again and live forever.

What Is The Difference Between A Medusa And A Polyp?
Cnidarians are a group of animals that includes jellyfish, corals, and anemones. These animals are distinguished by their possession of stinging cells called cnidocytes. Cnidarians can exist in two different body forms – the polyp and the medusa. The polyp is a sedentary, or sessile, form that is often attached to a substrate. The medusa is a free-swimming form that is typically bell-shaped.
One of the key differences between polyps and medusae is their method of reproduction. Polyps reproduce asexually, by a process called budding, in which a new individual grows from an outgrowth of the parent polyp. Medusae, on the other hand, reproduce sexually. Eggs and sperm are produced by different individual medusae and fertilization occurs when the eggs and sperm meet in the water.
Jellyfish are a type of cnidarian that typically exist in the medusa form. However, they go through a life cycle that includes both the polyp and medusa stages. The polyp stage of a jellyfish’s life cycle is spent attached to a substrate, often in groups. The medusa stage is the free-swimming, adult stage of the jellyfish. Jellyfish reproduce sexually, with eggs and sperm being released into the water by different individuals. Fertilization occurs when the eggs and sperm meet, and the resulting larva settles on the substrate, where it develops into a polyp. The polyp then asexually produces medusae, which mature and eventually reproduce sexually, starting the cycle anew.

Polyps reproduce asexually, while medusae reproduce sexually. Jellyfish go through a life cycle that includes both polyp and medusa stages.
How Does A Jellyfish Reproduce?
Jellyfish can reproduce both sexually and asexually. In sexual reproduction, male jellyfish release sperm into the water, which fertilizes eggs released by the female. The fertilized eggs develop into larvae, which eventually settle into the ocean floor and transform into polyps. The polyps reproduce asexually by budding, and each new polyp is a clone of the parent. The medusae (jellyfish) stage of the jellyfish lifecycle is generated from the polyps, and they can reproduce sexually by releasing sperm and eggs into the water, where fertilization and development into larvae occurs. The immortal jellyfish is able to revert back to its polyp stage when faced with adverse conditions, and in this way it can effectively achieve immortality.
Jellyfish can reproduce both sexually, by releasing sperm and eggs into the water for fertilization, and asexually, by budding from polyps. The immortal jellyfish can revert back to its polyp stage, effectively achieving immortality.
What Is The Lifespan Of A Jellyfish?
Jellyfish are fascinating creatures that have a very unique life cycle. Most jellyfish are short lived, with an adult medusa typically only living for a few months. However, some species of jellyfish can live for much longer periods of time. The immortal jellyfish, for example, is believed to have the ability to live forever.
In captivity, the lifespan of a jellyfish is often much different than in the wild. For example, the Lion’s Mane jellyfish is known to only live for a few days in the wild but can live for much longer periods of time in captivity.
Overall, the lifespan of a jellyfish depends on a variety of factors, including the species of jellyfish, the environment in which it lives, and whether it is in captivity or the wild.
The lifespan of a jellyfish varies depending on the species and the environment in which it lives. Some jellyfish can live for only a few days, while others, like the immortal jellyfish, may be able to live forever.
Do All Jellyfish Sting?
No, not all jellyfish sting. In fact, only a small percentage of jellyfish species have stinging cells on their tentacles, which release a venom that can paralyze their prey. Most jellyfish are harmless to humans and use their stinging tentacles primarily to catch and eat their dinner. Still, jellyfish stings are fairly common problems for people swimming, wading or diving in oceans. The long tentacles trailing from the jellyfish can brush against a person’s skin, causing a sting. Most jellyfish stings are not serious and can be treated with home remedies. However, some jellyfish species have venom that can be dangerous, even life-threatening. If you are stung by a jellyfish, it is important to seek medical attention immediately.

How Do Jellyfish Carry Their Babies?
There are a few jellyfish species that receive sperm through their mouths to fertilise eggs inside the body cavity, but most jellyfish just release sperm or eggs directly into the water. The eggs hatch into larval jellyfish, which eventually grow into adults.
How Many Babies Do Jellyfish Have?
Some jellyfish can lay as many as 45,000 eggs in a single night. This means that they have the potential to produce a large number of offspring. However, it is not known exactly how many babies jellyfish typically have.
Where Did Jellyfish Come From?
Jellyfish come from one of the oldest branches on the animal family tree, the phylum Cnidaria. This phylum includes corals and anemones, and jellyfish were probably the first muscle-powered swimmers in the open ocean.
What Is The Average Lifespan Of A Jellyfish?
The average lifespan of a jellyfish is a few months, but some species can live for up to a year or longer. The Turritopsis dohrnii is the only known biologically immortal jellyfish species.
Do Jellyfish Lay Eggs?
Yes, jellyfish can lay eggs. The process of reproduction for jellyfish is complicated and involves several different stages. In the adult, or medusa, stage of a jellyfish, they can reproduce sexually by releasing eggs and sperm into the water. The eggs are then fertilized by the sperm and develop into larvae. The larvae eventually settle into the bottom of the ocean and transform into polyps. Polyps can reproduce asexually by budding, while medusae spawn eggs that develop into larvae. There are a few jellyfish species that receive sperm through their mouths to fertilise eggs inside the body cavity, but most jellyfish just release sperm or eggs into the water to fertilize themselves.
How Does A Jellyfish Reproduce Asexually?
Jellyfish can reproduce both sexually and asexually. Asexual reproduction occurs when the jellyfish polyp colony buds off tiny jellyfish one or two millimetres across, which then feed on plankton and gradually grow into medusae.
FAQS
- Do Jellyfish Give Live Birth Or Lay Eggs?: Jellyfish generally lay eggs, though a few species give birth to live young. Octopuses lay eggs and do not give birth to live young.
- What Is Your Favorite Animal?: Many people have a favorite animal. This favorite animal can say something about a person’s personality and who they are as a person.
Final Word
Jellyfish are one of the most fascinating creatures in the ocean. They come in a variety of shapes and sizes, and their lifecycle is both strange and wonderful.
Jellyfish are born from polyps. These polyps attach to surfaces in the ocean and reproduce asexually by budding. The new jellyfish then break away from the polyp and begin their life as a medusa.
Medusae are the free-floating, jellyfish-like creatures that we are most familiar with. They reproduce sexually, and the eggs and sperm are released into the water. The eggs then hatch and the new jellyfish begin their life as a polyp.
This cycle then repeats itself, with the jellyfish alternating between the polyp and medusa stages. It’s truly amazing to think about how such a simple creature can have such a complex life cycle.
