No movement, no symmetry, the researchers found. In fact, it's the muscular movements caused by the jellyfish's regular pulsations that draw the limbs into place around the body.
"It's kind of beautiful that their normal swimming and feeding process leads to this self-repair. It's normal," Abrams said. The process occurs with as few as two remaining limbs and up to seven, he said.
In theory, the findings could inspire self-repairing materials, Abrams said.
"You don't need to rebuild lost parts," he said. "You're just reorganizing what you have."
The researchers reported their findings Monday (June 15) in the journal Proceedings of the National Academy of Sciences.
