Jellyfish Reverses Life Cycle to Escape Death
Scientists have discovered a special jellyfish called Turritopsis dohrnii that can live forever.
When it gets old or sick, it doesn't die like other animals.
Instead, it turns back into a baby jellyfish and starts its life all over again.
This amazing ability was first found in 1996, even though the jellyfish was discovered much earlier in 1883.
The jellyfish is very small, about the size of a little fingernail.
Scientists think studying this jellyfish might help them learn how to heal damaged tissues and organs in humans.
Even though this won't make people live forever, it could lead to new medical treatments.
The jellyfish belongs to a group called hydrozoans, which are related to true jellyfish.
Other famous creatures in this group include the Portuguese Man o' War.
Turritopsis dohrnii jellyfish can reverse its life cycle to avoid death and rejuvenate.
Discovered in 1883, its special ability was found in 1996.
Size is about 4.5 millimeters, less than a little fingernail.
Belongs to the hydrozoan family, related to true jellyfish.
Scientists believe studying this jellyfish could lead to new medical treatments for tissue and organ repair.
