A species of jellyfish known as Turritopsis nutricula can do something no other animal can pull off: It can regenerate its body. And it can do this over and over again, apparently sustaining its life indefinitely.
Some animals can regrow certain limbs and organs, but Turritopsi nutricula can regenerate its entire body over and over again. Researchers are studying the jellyfish to discover how it is able to reverse its aging process.
Because they are able to bypass death, the number of individuals is spiking. They’re now found in oceans around the globe rather than just in their native Caribbean waters. “We are looking at a worldwide silent invasion,” says Dr. Maria Miglietta of the Smithsonian Tropical Marine Institute.
