It’s captivated scientists since it was discovered decades ago. Like lots of marine species, the 'immortal jellyfish' was discovered by accident. • The immortal jellyfish propagate and then, in the face of death, they opt instead to revert to a sexually immature stage. It can skip several life cycle stages and revert to an earlier stage of development, at which point it begins its life cycle again. Consider a butterfly that, instead of dying, turns back into a caterpillar. • The immortal jellyfish was discovered in the Mediterranean Sea in 1883 but the unique ability was not discovered until the 1990s. They prefer warmer waters, although they have been spotted in colder areas as well. They originate in the Caribbean and the Mediterranean Sea. • This amazing creature is proving to be able to survive in any ocean and temperatures and is making its way across the globe. Their diet consists of plankton, fish eggs and small molluscs. Younger jellyfish have only eight tentacles and are 1mm tall, while adults can have up to 90 tentacles and can reach a maximum of 4.5 mm which is about as wide as a human pinky. • Once they have reproduced by the meeting of free-floating sperm and eggs.., they don’t die but transform themselves back into their juvenile polyp state. Their tentacles retract, their bodies shrink, and they sink to the ocean floor and start the cycle all over again and they can do it over and over again. However, most of the time they die normally, when starvation, physical damage, or other crises arise, they transform all of its existing cells into a younger state to avoid certain death. • It turns itself into a bloblike cyst, which then develops into a polyp colony,.In this process the cells are transformed, muscle cells can become nerve cells etc. Through asexual reproduction, the resulting polyp colony can spawn hundreds of genetically identical jellyfish—near-perfect copies of the original adult. Some cells of this jellyfish that are supposed to die are able to switch off some genes and to switch on some other genes, reactivating genetic programs that were used in earlier stages of the life cycle. • • Genetically hydra are the same as human beings. We’re variations of the same theme so we aren’t dealing with something that's completely different to us! So what do you think? Can humans evolve and become immortal ourselves or is this ecological nonsense. • Thanks for watching today guys, as usual, if you enjoyed the episode give me a like and hit that bell for future episodes. • References: • Turritopsis rubra medusa; copright P.
