Certain species of sea cucumbers, like Psolus fabricii, exhibit an astonishing form of regeneration where detached body parts can survive for years. These 'zombie' appendages scavenge nutrients from seawater, maintaining cellular division and tissue integrity independently of the main organism.

This remarkable survival, coupled with rapid wound healing and observed neural preservation in detached tentacles, offers significant potential for biomedical research. Scientists are studying these processes to advance tissue engineering and develop new methods for human tissue repair.
