The immortal jellyfish is a type of jellyfish that can revert to an earlier stage of development if injured or threatened.

When a jellyfish is damaged or stressed, it shrinks on its own, reabsorbs its tentacles, and settles on the seafloor as a cyst.

After 24-36 hours, the cyst turns into a polyp, the jellyfish’s previous life stage.

The polyp then matures and buds from the medusa, the classic jellyfish with a bell-shaped body and tentacles.

Immortal jellyfish were first discovered in the Mediterranean in the 1880s.

The immortal jellyfish is only 4.5 millimeters in diameter when fully grown

The immortal jellyfish comes in two forms: the classic jellyfish medusa and the polyp, the baby form of the jellyfish.

The process by which immortal jellyfish revert to an earlier stage of development is called transdifferentiation, and it is extremely rare.
