Immortal Jellyfish: Can They Really Live Forever?
These jellyfish have been around since 1883 and they have infinite lives!
Does the secret to immortality reside in the ocean? Much like Vampires, the Turritopsis nutricula jellyfish is one of a few known species known to live forever.
These amazing jellyfish have the extraordinary ability to regenerate their cells in times of crisis -- when they are harmed or malnourished, they can morph from a baby to an adult and after mating, back to a baby to start life all over again. They are often compared to Benjamin Button.
They are often referred to as 'Wolverine of the Sea.'
They cling on to a surface in warm ocean waters and transform into a blob. They then undergo a process called "transdifferentiation," when the cells transition into different types of cells. Muscle cells can turn into eggs or sperm, or nerve cells can become muscle cells, "revealing a transformation potential unparalleled in the animal kingdom," according to this study which was conducted by several biologists in 1996.
However, Turritopsis can die if they succumb to disease or are killed by predators but these creatures will never die of natural causes.
