Behold Turritopsis nutricula the Eternal Jellyfish, the Immortal One, the Jack Harkness of the invertebrate world.

Essentially, sexually mature jellyfish spawn and die. This doesn't. It reverts to the sexually immature form and goes on living. To quote Wikipedia:

Theoretically, this cycle can repeat indefinitely, rendering it biologically immortal until its nerve center is removed from the rest of the body.

Loosely paraphrased, it lives forever unless you cut its head off. Great. Does this remind you of anything?

The ability to reverse the life cycle is probably unique in the animal kingdom, and allows the jellyfish to bypass death...

Lord Voldemort would be proud.

Since the species is immortal, the number of individuals is spiking. "We are looking at a worldwide silent invasion" said Smithsonian Tropical Marine Institute scientist Dr. Maria Miglietta.

HELP!
