Summary
Researchers studying the sea cucumber Psolus fabricii from the North Atlantic made an unexpected discovery: severed fragments of the creature did not decay and die as expected, but instead continued living and even appeared to grow. This phenomenon, described as 'tissue immortality,' challenges conventional understanding of life and death in biological organisms and raises new questions about cellular regeneration and survival mechanisms.

Some amputated fragments of Psolus fabricii — a type of sea cucumber native to the North Atlantic Ocean — puzzled researchers when they noticed that the severed parts did not simply decay and die but instead appeared to grow.
To find out more, the researchers humanely excised additional fragments from the feet, main body and tentacles of the marine animal.
