Immortality is a gift of nature!

Posted on 04 June 2012 by RE Team

Immortality is one of the fascinations of humans. It may be a science fiction for us, it’s not a wonder for nature. But, nature has gifted immortality to one of the species already. The only known species in Earth with biological immortality is “Turritopsis nutricula“. This species is a type of Jellyfish can be of the size of a human nail (diameter of about 4.5 millimeters) when fully developed.

 

The immortal Turritopsis Nutricula

 

Immortality is one of the fascinations of humans. It may be a science fiction for us, it’s not a wonder for nature. But, nature has gifted immortality to one of the species already. The only known species in Earth with biological immortality is “Turritopsis nutricula“. This species is a type of Jellyfish can be of the size of a human nail (diameter of about 4.5 millimeters) when fully developed.

The Jellyfish has achieved the immortality through a biological cell development process, called transdifferentiation. Cell transdifferentiation is when the jellyfish “alters the differentiated state of the cell and transforms it into a new cell. With this process, the species can revert to the polyp stage, a sexually immature, colonial stage, after becoming sexually mature. Theoretically, this process can go on infinitely, effectively rendering the jellyfish biologically immortal. No single specimen of this Jellyfish has been observed for any extended period, so it is impossible to estimate the age of an individual.

This species was first discovered in 1883. However, it wasn’t until the 1990s that this unique ability to transform back into younger self once it has become sexually mature and has mated was uncovered. Many marine biologists and geneticists are now studying the jellyfish in order to determine how it is able to reverse its aging process.

Turritopsis is believed to have originated in the Caribbean but has spread all over the world. It is believed to be spreading across the world as ships are discharging ballast water in ports. Since the species is immortal, the number of individuals could be spiking. Are we on the verse of a a worldwide silent invasion??
