well, technically it's not immortal, it's just not subject to the usual aging process leading to death...

Turritopsis nutricula, the potentially immortal jellyfish, is a hydrozoan whose medusa, or jellyfish, form can revert to the polyp stage after becoming sexually mature. It is the only known case of a metazoan capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary stage.[2][3] It does this through the cell development process of transdifferentiation. Cell transdifferentiation is when the jellyfish "alters the differentiated state of the cell and transforms it into a new cell." In this process the medusa of the immortal jellyfish is transformed into the polyps of a new polyp colony.

yeah, i remember watching a doccie on this species of giant jellyfish.
basically, due to jap overfishing and global warming, jellyfish populations exploded.
their trawler nets consequently were filled with these mammoth jellies.
they then started slicing and dicing them before returning them back to the ocean.
problem is that when jellyfish are put under pressure, they release eggs and sperm en masse, so basically japanese fishermen were sealing their own fate...

Evolution wise that is brilliant. But also disgusting.

Imagine humans having orgasms just before getting killed..

Not just orgasms... lots and lots and lots and lots of orgasms. Actually, it'd probably curb crime a bit.

After enjoying sex as an adult instead of growing old like normal, it just transform to a child again till it wants to go at it again.
