Is immortal jellyfish rare?

This phenomenon has been likened to that of a butterfly which, instead of dying, would be able to transform back into a caterpillar and then metamorphose into an adult butterfly once again. The process behind the jellyfish's remarkable transformation is called transdifferentiation and is extremely rare.

How do jellyfish live without a brain?

So how do they function without a brain or central nervous system? They have a basic set of nerves at the base of their tentacles which can detect touch, temperature, salinity etc. Since they don't have a brain, they depend on automatic reflexes in response to these stimuli! Catching prey is also a matter of chance.
