Immortal Sea Creature Resets Lifespan Like A Video Game Character

Immortal jellyfish are strange and fascinating creatures, native to tropical waters. While they age in a straightforward process from tiny, fingernail-sized larvae into sprawling adults with tentacles reminiscent of Medusa’s snaky waves, their life cycle is quite unlike any other creature on Earth.

At times when other jellyfish would be stressed enough to shuffle off their mortal coil, the immortal jellyfish simply reverses its life cycle, shrinks back into its larval state, and births a set of mini selves, essentially restarting their lives from scratch.
