Transcript of Untitled Prezi

By: Steven, Tahreem Turritopsis Nutricula Have you ever thought about if we had the choice to reverse our life cycle whenever we wanted to? If we were given another chance to live again? Well, Turritopsis Nutricula is the only living thing in this world that has achieved immortality!
Turritopsis Nutricula Life cycle Life cycle YouTube video Scientific Classification Habitat The “immortal jellyfish” can be found all across the world although it is believed to have originated in the Caribbean Sea
It can be found in both temperate to tropical regions in all of the world’s oceans
This uncontrollable spread is believed to be caused by the ships discharging water ballast in all of the ocean ports
http://www.tumblr.com/tagged/turritopsis%20nutricula Description The Medusa or “umbrella head” is about 4.5 millimeters in diameter

It is as wide as it is long

The Medusa is bell-shaped and contains uniformly thin jelly

The bright red object present just under the Medusa is actually the stomach of the jellyfish

It has about 80-90 tentacles by the time it reaches adulthood Typical life cycle of a regular jellyfish:

The sperm released by the male jellyfish comes in contact with the egg that is present in the stomach of female jellyfish.
The fertilized eggs separate themselves from their mother’s stomach and develop into planulae. The planulae eventually sink to the bottom of the ocean and settle on the floor and shape into a polyp which resembles a sea plant.
These polyps form buds by growing multiple identical polyps until it becomes a colony. These buds of polyps release free-floating immature Medusa about 1 mm in size which develops into plankton after a few weeks.
Life cycle of Turritopsis Nutricula:
Apart from other jellyfish species, Turritopsis Nutricula has a unique ability to return to the polyp state after reproducing sexually , by a specific transformation process that requires the presence of certain cell types.
When Turritopsis Nutricula transforms back into a polyp it restarts the process of asexual reproduction How it Becomes Immortal Turritopsis Nutricula changes into the polyp stage through the cell development process of transdifferentiation. During this process it transforms all of its existing cells into a younger state. The jellyfish’s cells could completely transform in this process. Existing muscle cells could turn into egg or sperm cells in the new jellyfish. "We are looking at a worldwide silent invasion", said Smithsonian Tropical Marine Insitute scientist Dr. Maria Pia Miglietta.

Thank you for listening :) kingdom: Animalia
Phylum: Cnidarian
Class: Hydroza
Order: Anthomedusae
Genus: Turritopsis


1) First, the umbrella reverts itself and then the tentacles.
2) Then the resorption of the tentacles and mesoglea occurs.

3) The reverted medusa then attaches itself to a substrate at the bottom end of the medusa and starts giving rise to new polyps to form the new colony.

4) Theoretically, this process can go on infinitely, effectively rendering the jellyfish, immortal. 
What If? If immortality is already achievable in nature, what is the future of medicine going to hold?
Could we expect an invasion, and overpopulation of this jellyfish?
Could we expect an overpopulation and invasion of ourselves if we could achieve this?
