Immortal jellyfish are strange and interesting animals, native to tropical waters. While they age in a linear process from tiny, fingernail-sized larvae to sprawling adults with tentacles reminiscent of Medusa’s serpentine waves, their life cycle is unlike any other creature on Earth.
Sometimes when another jellyfish was stressed enough to shrug off its mortal coil, the immortal jellyfish would simply reverse its life cycle, revert back to its larval state, and give birth to a set of tiny stems, starting their lives all over again.
