Lantern Jellyfish – Do They Really Live Forever?

Lantern jellyfish are the most extraordinary creatures, who are said to live forever. But do they really? As much as we’d like to believe they do, sadly they don’t. Lantern jellyfish, like other jellyfish, have some of the most perplexing lifespans, which we are still trying to uncover more thoroughly.

Lantern jellyfish are definitely longer-lived than most jellyfish – instead of the average 3 month lifespan, it’s thought that they can live up to 12 months in the wild. They are incredibly hardy and have been known to withstand ages of extremes, from flooding and drought to even acidic environments. This incredible resilience leads to speculation of them living forever, but sadly this isn’t the case.

One factor which is thought to influence their longevity is the concentration of bioluminescent bacteria found in the jellyfish’s bulbs. Studies have shown that these bacteria actually accumulate over time and can create an antioxidant effect which helps to prolong the lifespan of the jellyfish – meaning that the more bioluminescent bacteria a lantern jellyfish has, the more likely they are to live longer.

Another factor which has been thought to significantly affect the lifespan of lantern jellyfish is the number of predators that they encounter. As with any other creature, if a lantern jellyfish is constantly being predated upon, this puts increased pressure on its lifespan. So, whilst it might seem like some lantern jellyfish populations have no predators and have been reported to have lived for longer, this is more likely due to the reduced predation pressure in these particular environments.

And finally, the overall health of the individual jellyfish is critical in maintaining a long lifespan. As these jellyfish feed on primarily planktonic prey, it is important that they receive regular and good amounts of nutrition in order to remain healthy for longer. This increases the chances of the jellyfish reaching its full potential lifespan.

Whilst lantern jellyfish do definitely have a much longer lifespan than other jellyfish, sadly they don’t live forever. However, due to their hardiness and resilience, as well as their ability to survive extreme environments, they are a great candidate organism to help us understand the effects of climate change and other environmental pressures on an organism.
