. Dohrnii goes through a two-part life cycle living on the sea floor during an asexual phase where its chief role is. Scientists in Spain have unlocked the genetic code of the immortal jellyfish - a creature capable of repeatedly reverting into a juvenile state - in hopes of unearthing the secret to their unique longevity and find new clues to human aging. 1 day agoScientists in Spain have unlocked the genetic code of the immortal jellyfish - a creature capable of repeatedly reverting into a juvenile state -.

To date theres only one species that has been called biologically immortal. The jellyfish Turritopsis dohrnii. These small transparent animals hang out in oceans around the world and can turn back time.

These ultimately spawn free-swimming genetically identical medusaethe animals we recognize as jellyfishwhich grow to adulthood in a matter of weeks. Some modern species may possess biological immortality. The jellylike creatures pulse along on ocean currents and are abundant in cold and warm ocean water in deep water and along coastlines.

When the medusa the immortal jellyfish Turritopsis dohrnii dies it sinks to the ocean floor and begins to decay. If the start of jellyfish life wasnt extraordinary enough its death is where things get really exciting.

When the jellyfish ages it will settle onto the sea floor and become polyps which then spawn new genetically identical jellyfish. Like other types of jellyfish the T. Others include the jellyfish Laodicea undulata.
