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 reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual.
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 world.
Turritopsis nutricula McCrady, 1857 (several species, including the "immortal jellyfish", were formerly classified as T. nutricula) [4] Turritopsis pacifica Maas, 1909; Turritopsis pleurostoma (Péron & Lesueur, 1809) – species inquirenda; Turritopsis polycirrha (Keferstein, 1862) Turritopsis rubra Farquhar, 1895
Immortal jellyfish can still die, from predation and disease, but their regenerating abilities make them tough and successful. ... Believe or not, if there’s a threat, trees don’t always allow ...
The medusae of most species are fast-growing, and mature within a few months then die soon after breeding, but the polyp stage, attached to the seabed, may be much more long-lived. Jellyfish have been in existence for at least 500 million years, [1] and possibly 700 million years or more, making them the oldest multi-organ animal group. [2]
Turritopsis nutricula is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. This adaptive trait likely evolved in order to extend the life of the individual.
Scientists don't know how or why this particular jellyfish ended up in the Gulf. When we think of exploration, we normally think of space , but perhaps even greater mysteries lie in our oceans .
