Why / How?

01

Scientific Mechanism

This rare process, called transdifferentiation, allows specialized adult cells to revert into stem-like cells and rebuild a young polyp colony. While it can theoretically repeat this cycle indefinitely, it can still be eaten by predators.

02

Why It Matters

Through transdifferentiation, mature specialized cells convert back into juvenile polyp cells, restarting the life cycle.
