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. A new promising approach comes from the cnidarian Turritopsis dohrnii. Most animals reproduce, age, and die. T. dohrnii has escaped this fate.

She compared T. dohrnii and its close relative, Turritopsis rubra (T. rubra), another species of jellyfish that is genetically similar to T. dohrnii but is mortal. This research focused on comparing gene structure and gene expression related to aging between the two species by analyzing DNA samples between the two jellyfish and looking at RNA ... Now T. dohrnii jellyfish can be eaten by bigger creatures – so they are not truly immortal. But when T. dohrnii suffers a physical attack, or starvation, or some kind of environmental stress, instead of dying, they change firstly into a tiny blob, and then back to the polyp stage within 3 days. They become another polyp colony sitting on a rock.Dec 3, 2019 · The polyp, medusa and cyst of T. dohrnii were sequenced through Illumina RNA-sequencing and assembled using a de novo approach, resulting in 92,569, 74,639 and 86,373 contigs, respectively.
