one to three years.
Most jellyfish live one to three years, but certain species can live from days to decades. Jellyfish have complex life cycles, beginning with fertilized larvae floating in the ocean.
Can jellyfish live for 1000 years?
The jellyfish Turritopsis nutricula is biologically immortal and could, under ideal conditions, live for 1000s of years. After sexually reproducing, this jellyfish can revert back to the immature polyp stage (back into a “child”). The jellyfish can still die due to predation, but aging is not a problem for it.
Can jellyfish live for millions of years?
There is a species of jellyfish that is basically immortal.
T. dohrnii can go back and forth between its polyp and medusa stages, leading to it being known as “the immortal jellyfish.” Further research shows that other species of jellyfish may be able to reserve-age, too.
Are jellyfish friendly?
Jellyfish are found in every ocean around the world and prefer to live in coastal areas. Some jellyfish are harmless to humans but others have venom that can be very deadly. The box jellyfish is one of the most venomous animals on the planet!
How old is the oldest jellyfish?
Domestic jellyfish live anywhere from one to three years. Wild species can live anywhere from a few days to decades. One species in particular, dubbed the ‘Immortal Jellyfish’ (Turritopsis dohrnii) may actually live forever.
Do jelly fish feel pain?
Can jellyfish feel pain? Jellyfish don’t feel pain in the same way that humans would. They do not possess a brain, heart, bones or a respiratory system. They are 95% water and contain only a basic network of neurons that allow them to sense their environment.
Are jellyfish asexual?
Throughout their lifecycle, jellyfish take on two different body forms: medusa and polyps. Polyps can reproduce asexually by budding, while medusae spawn eggs and sperm to reproduce sexually.
Can jellyfish sting when dead?
The tentacles of the jellyfish have tiny stingers called nematocysts which can detach, stick to skin, and release venom. Even if the jellyfish is dead, it can still sting you because the cell structure of nematocysts is maintained long after death.
Do jellyfish know they are alive?

Is it cruel to keep jellyfish as pets?
Keeping jellyfish in an aquarium is no crueler than keeping a plant in a plant pot. In the wild mortality rates are exceedingly high with only a few jellies in every thousand reaching maturity due to natural predation and beaching.
What happens if you cut a jellyfish in half?
If you cut a jellyfish in half, the pieces of the jellyfish can regenerate and turn into two new jellies.
Are jellyfish smart?
Jellyfish are not very smart. “They have very simple sensory organs, and no brain to process any information,” says marine biologist Stein Kaartvedt. Which is why it’s so interesting that, off the coast of Norway, scientists have observed what they’re calling “apparent social behavior” in the helmet jellyfish.
What kills the immortal jellyfish?
While an immortal jellyfish can age in reverse, it can also be easily killed by predators including various fish, sharks, turtles and even other jellyfish.
Do jellyfish make noise?
Jellyfish are unable to make sounds, other than the movement they make as they swim through the water.
Do jellyfish have emotion?
Honeybees display pessimism and jellyfish make complex decisions using a brain. Just when you think you’ve heard it all, two recent research projects have discovered that honeybees have emotional lives and the nervous system of jellyfish and their behavior is far more complex than previously thought.
Can jellyfish change gender?
Other species of jellyfish – sequential hermaphrodites – are either male and then female, or vice-versa, but not both simultaneously. These are natural transgender jellyfish. No special treatment is necessary.
