Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish [2] [3] found worldwide in temperate to tropic waters. It is one of the few known cases of animals capable of completely reverting to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual.
Most living creatures are bound by the fact of birth, aging and death. Few, however, have evolved to break the typical life cycle. The aptly named immortal jellyfish (Turritopsis dohrnii) is one ...
The Turritopsis dohrnii is believed to be the only creature in existence capable of continuous. For centuries humans have searched far and wide for a way to live forever. Meanwhile, a species of ...
The study was aimed at understanding what made this jellyfish different by comparing the genetic sequence of T. dohrnii to that of Turritopsis rubra, a close genetic cousin that lacks the ability ...
Turritopsis dohrnii, or Turritopsis nutricula, is a small (5 millimeters (0.20 in)) species of jellyfish that uses transdifferentiation to replenish cells after sexual reproduction. This cycle can repeat indefinitely, potentially rendering it biologically immortal. This organism originated in the Caribbean Sea, but has now spread around the ...
Turritopsis dohrnii repeats this cycle, meaning that it may have an indefinite lifespan. [30] Its immortal adaptation has allowed it to spread from its original habitat in the Caribbean to "all over the world". [31] [32] Hydra is a genus belonging to the phylum Cnidaria, the class Hydrozoa and the order Anthomedusae.
Only a few exceptions defy this pattern, such as the “immortal jellyfish” Turritopsis dohrnii, known for its ability to revert from an adult medusa to a polyp stage.
Individuals of other species have been observed to regress to a larval state and regrow into adults multiple times. The hydrozoan species Turritopsis dohrnii (formerly Turritopsis nutricula) is capable of cycling from a mature adult stage to an immature polyp stage and back again.
