Why do they call it the immortal jellyfish?
In a process that looks remarkably like immortality, the born-again polyp colony eventually buds and releases medusae that are genetically identical to the injured adult. In fact, since this phenomenon was first observed in the 1990s, the species has come to be called “the immortal jellyfish.”
Who discovered Turritopsis Dohrnii?
dohrnii was first described by scientists in 1883. It was 100 years later, in the 1980s, that their immortality was accidentally discovered. Students Christian Sommer and Giorgio Bavestrello collected Turritopsis polyps, which they kept and monitored until medusae were released.
Why is Turritopsis Dohrnii immortal?
In nature, most Turritopsis dohrnii are likely to succumb to predation or disease in the medusa stage without reverting to the polyp form. The capability of biological immortality with no maximum lifespan makes T….Turritopsis dohrnii.

Can a Turritopsis Dohrnii die?
Of course, Turritopsis dohrnii isn’t truly ‘immortal’. They can still be consumed by predators or killed by other means. However, their ability to switch back and forth between life stages in response to stress means that, in theory, they could live forever.
Who discovered Turritopsis nutricula?
Giorgio Bavestrello
As with so many findings, the so-called ‘immortal jellyfish’ was discovered by accident. During a visit to my laboratory in the 1980s, a German student, Christian Sommer, and my very first student, Giorgio Bavestrello, collected a hydrozoan thought to be Turritopsis nutricula.
Is owning a jellyfish legal?
Question: Are jellyfish legal to own in California? Answer: Yes.
What is the oldest animal on earth right now?
Seychelles giant tortoise
Oldest land animal (living) Jonathan, a Seychelles giant tortoise, is the oldest land animal alive in the world. He is believed to have been born in 1832, making him 189 years old in 2021. Originally from the Seychelles, he is a long-time resident of the remote South Atlantic island of St Helena.
What does the Turritopsis Dohrnii eat?
They eat plankton, tiny molluscs, larvae and fish eggs. They might be ‘kind of immortal’, but the immortal jellyfish are not impervious to all threats.
Is Turritopsis dohrnii a human introduced species?
Maria Pia Miglietta, a research professor from the University of Notre Dame, has identified a human mediated, worldwide introduction to the hydrozoan species Turritopsis dohrnii. The normal life cycle of hydrozoans involves the asexual budding of the medusa, or jellyfish, form from colonial polyps.
Is Turritopsis dohrnii a medusa?
Turritopsis dohrnii was first described from Naples, Italy, and is a common hydroid on rocky substrates in the Western Mediterranean and Adriatic. However, it is less well-known in this region as a medusa (Schuchert 2004).
How many species of Turritopsis are there?
A genetic study of Turritopsis identified seven species from the Atlantic and Pacific, four of which are unnamed (Miglietta et al. 2006). Turritopsis dohrnii, described from the Mediterranean, has a disjunct distribution and genetic similarity indicative of human-mediated introduction (Miglietta and Lessios 2009).
Where can I find Turritopsis in Panama?
Miglietta and Lessios (2009) surveyed populations of Turritopsis spp. at many locations in the Atlantic and Pacific in 2002-2009. On the Caribbean coast of Panama, medusae of T. dohrnii were found at Galeta Island, near the Panama Canal entrance, this hydrozoan was also found in many samples in Bocas del Toro, about 200 km west of the Canal.
