- Groxx 17y agoYeah, I think there are a few animals like that. So while it's not likely the only "immortal" animal, this jellyfish does definitely seem to have a unique kind of immortality.
- sambeau 17y agoMost living things are 'immortal' in that they do not age. This is true of bacteria, fish, lobsters, birds etc. It just happens that most creatures we have close contact with - i.e. Mammals, do. What is unusual about this Jellyfish is not it's lack of ageing, but it's ability to return to "childhood" at times of stress and then become an adult once again, later. It's a weird and fascinating concept for us Mammals. Although I am pretty sure I wouldn't want to repeat my teenage years over and over.
