One of the most popular jellyfish, the moon jellyfish (Aurelia aurita), is known to have a lifespan of 12 to 18 months but with proper living conditions, can live up to 20 years. The Flame jellyfish (Rhopilema esculentum) has a rather shorter lifespan as it can only live from three months up to a maximum of one year..
Also question is, can jellyfish live forever?
Scientists have discovered a jellyfish which can live forever. Turritopsis dohrnii is now officially known as the only immortal creature. It turns out that once the adult form of the 4.5 mm-wide species Turritopsis dohrnii have reproduced, they don't die but transform themselves back into their juvenile polyp state.
One may also ask, can jellyfish die of old age? Theoretically, this process can go on indefinitely, effectively rendering the jellyfish biologically immortal, although in practice individuals can still die. In nature, most Turritopsis are likely to succumb to predation or disease in the medusa stage, without reverting to the polyp form.
Also asked, what is the lifespan of a jellyfish?
It of course depends on the species of jellyfish. The lifespan can range from several hours (for hydromedusaes) to a few months for large coastal jellyfish (usually 2-6 months). However, there are some outliers: There is one jellyfish species that has been reported to live up to 30 years.
Is there a jellyfish that never dies?
An 'immortal' jellyfish is swarming through the world's oceans, according to scientists. The Turritopsis Nutricula is able to revert back to a juvenile form once it mates after becoming sexually mature. Marine biologists say the jellyfish numbers are rocketing because they need not die.
