Discovering immortal animals on Earth

American scientists have discovered the strange life cycle of a jellyfish whose scientific name is turritopsis nutricula .

This marine layer of jellyfish can reverse their life cycle from adulthood back to the single-celled period and from there continue to grow.

Their life cycle is constantly repeated making this jellyfish identified as the only immortal animal on Earth today.

US scientists believe that the secret of turning jellyfish on the timing wheel is the process of "cell transduction," whereby one type of cell can be transformed into another.

Some animals also have this ability but are very limited, like salamanders that can re-grow limbs.

The jellyfish turritopsis nutricula has the ability to constantly regenerate the whole body. This ability is still a secret of nature and is being decoded by scientists.

According to the scientists, because of immortality, the marine jellyfish species originating in this Caribbean sea has quietly invaded the world. They are present in all oceans around the globe.
