Did you know that there is a kind of jellyfish that is immortal?

The only immortal species on Earth is a transparent jellyfish called Turritopsis nutricula that measures up to a maximum of 4.5 millimeters. Did you know?

He is able to return to his juvenile form (polyp) after reaching his sexual maturity, through a cellular process of transdifferentiation. Theoretically, this cycle can be repeated indefinitely, presenting itself as biologically immortal.

There are two stages in the life cycle of this jellyfish, polyp stage (juvenile) and the jellyfish stage (adult). They start as eggs and begin to hatch in two days. In two weeks they enter the jellyfish stage. Once the jellyfish reaches the jellyfish stage and mates, it begins to return to the polyp stage.

This species was originally discovered in 1880, but it was not until the 1990s that scientists discovered its ability to live theoretically forever.

It is found in all the oceans of the world in temperate or tropical waters, from Colombia to Japan, but it has also been found in the Mediterranean Sea on the coasts of Italy and Spain.

It should be noted that these jellyfish technically have the ability to live forever, but can die easily. They can be easily killed by a series of predators that use them as a source of food.
