Published on 13 May 2021 "Lobsters and jellyfish are considered biological [ly] immortal," reads a graphic circulating on Facebook in South Africa. While it's unlikely that sea anemone or flatworm stem cells could be compared one on one to a human stem cell, the basic principles of how these stem cell populations are maintained, how they are activated and the genes they use to develop into the regenerated structures are important to study.". Throughout the course of history, both science and religion have struggled to unlock the secret to overcoming senescence (biological deterioration, brought about by the loss of our cells power to divide and grow). Like the lobsters they use telomerase to protect their DNA and prevent cell death. Scientists have discovered a jellyfish which can live forever.

It is possible, however, that with the right environment and care, lobsters could live much longer than what is known. However, scientists are unable to say definitively how long jellyfish live due to their complex life cycles. They have segments. Turritopsis dohrnii, the so-called "immortal jellyfish," can hit the reset button and revert to an earlier developmental stage if it is injured or otherwise threatened. They can be caught and thrown into a pot, then smothered in bchamel sauce.
