16+ Immortal Jellyfish Polyp Stage Background. A jellyfish larva first develops into a polyp and it is this polyp that will then asexually produce thousands of jellyfish. While in their medusa stage, the jellyfish can revert back to the polyp stage.

The tiny jellyfish grows into a jellyfish start out as small larvae, which settle onto the seafloor and form a colony of polyps. A potentially immortal jellyfish species that can age backward the benjamin button of the deep is silently invading oceans, swarm by swarm, a recent study says. Like other jellyfish, it goes through two main stages of life, polyp and medusa.

One of the first researchers to study it this small, predatory marine invertebrate has two stages in its life cycle:

It is the only known case of a metazoan capable of reverting completely to. With two fine metal picks, he began. The tiny jellyfish grows into a jellyfish start out as small larvae, which settle onto the seafloor and form a colony of polyps. When the jellyfish come under stress again, they can repeat the process, reverting back to the polyp stage and then growing a colony once more, this process makes them potentially immortal.
