Never gets old. The immortal jellyfish can actually reverse its aging process and go backward through its life stages. When it gets old or sick, it transforms back into a young, immature form and starts growing up all over again.

Travels the world. These remarkable jellyfish live in oceans all over the globe, from cooler temperate waters to warm tropical seas. They are small creatures that float wherever ocean currents take them.

Changes its whole body. Most animals grow up and stay grown up, but this jellyfish can completely transform itself. It goes from being a grown-up jellyfish back to being a stationary polyp, which is like a tiny plant-like stage of its life.

Biological mystery. Scientists are still figuring out exactly how this jellyfish accomplishes something that breaks all the rules of aging. Understanding its secret could teach us amazing things about how living things grow and age.

Tiny but mighty. Despite its incredible powers, the immortal jellyfish is actually very small and easy to miss in the ocean. Its size makes its biological abilities even more mysterious and surprising.
