The ultrastructural study of the cellular modifications (during the life cycle reversion of T. nutricula) showed the presence of both degenerative and apoptotic processes. [4], Turritopsis nutricula in any point of the medusa stage has the ability to transform back into its polyp stage. Like most hydrozoans, Turritopsis passes through two main stages of life, polyp and medusa.

Turritopsis nutricula is a small jellyfish that once reaching adulthood, can transfer its cells back to childhood. Degeneration was prevalent during the unhealthy medusa and four-leaf clover stages, while the apoptotic rate was higher during the healthy medusa and cyst stages. The medusa, under stressed conditions, develops back to the polyp stage. 2 Like all jellyfish, it has no brains nor a heart provided by World Register of Marine Species. T. dohrnii falls under the last category. pacifica from Sagami Bay by Maas in 1909.

"Regeneration in Medusa buds and Medusae of Hydrozoa". Its official name is Turritopsis dohrnii (it used to be called Turritopsis nutricula). This regression from medusa to polyp has only been observed with the presence of differentiated cells from the outer umbrella and part of the animals digestion system. The polyp stage is benthic, with the cells forming colonies, while the medusa stage is a singular, planktonic organism. Turritopsis nutricula is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. Turritopsis nutricula is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. A morphological study of different stages during the reverted life cycle of Turritopsis nutricula led to the characterization of four different stages: healthy medusa, unhealthy medusa, four-leaf clover and cyst. Next article No Access DEVELOPMENT AND REPRODUCTION Reversing the Life Cycle: Medusae Transforming into Polyps and Cell Transdifferentiation in Turritopsis nutricula (Cnidaria, Hydrozoa) [2], Hydrozoans have two distinct stages in their life, a polyp stage and a medusa stage. Formerly known as Turritopsis nutricula, the creature capable of such an amazing feat is a very specialized jellyfish. Turritopsis nutricula, which originated in the Caribbean (but has spread throughout the world's oceans) is currently the only known organism where transdifferentiation (the irreversible transformation of cells from one differentiated type to another) takes place on an organismic level even though its individual parts, by themselves, are incapable of regeneration. [3] In T. nutricula, planktonic medusa have the capability to bud polyps or medusae which also have the ability to spawn new medusae. This adaptive trait likely evolved in order to extend the life of the individual. Die Medusen von Turritopsis dohrnii sind 2,7 Millimeter hoch und haben einen Durchmesser von 3,2 Millimeter.

Turritopsis nutricula (highlander jellyfish) is a hydrozoan with a life cycle in which it reverts to the polyp stage after becoming sexually mature.It is the only known case of a metazoan capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary stage. Die 14 bis 32 Tentakel sind manchmal am terminalen Ende verdickt. The hydrozoa life cycle is characterized, in normal conditions, by the alternation of a post-larval benthic polyp and an adult pelagic medusa; however, some species of Hydrozoa react to environmental stress by reverting their life cycle: i.e. Several different species of the genus Turritopsis were formerly classified as T. nutricula, including the "immortal jellyfish" which is now classified as T. Turritopsis nutricula is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. Turritopsis nutricula is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. It belongs to the Phylum Cnidaria. Like all jellyfish, Turritopsis dohrnii begins life as a larva, called a planula, which develops from a fertilized egg.A planula swims at first, then settles on the sea floor and grows into a cylindrical colony of polyps. Die Ocelli (Lichtsinnesorgane) sind rostfarben. This very uncommon life cycle could be considered as some sort of inverted metamorphosis. Polyps are sessile creatures that stay attached to a substratum. Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jellyfish found worldwide in temperate to tropic waters. A Turritopsis nutricula egy olyan hidraállat fajta, amelynek a medúza alakja visszaalakulhat polippá a teljes szexuális differenciálódása után is.

[2] It does this through the cell development process of transdifferentiation. Generally in hydrozoa the medusa develops from the asexual budding of the polyp and the polyp results from sexual reproduction of medusae. Turritopsis cf. This adaptive trait likely evolved in order to extend the life of the individual. 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. [5] The ability of transdifferentiation, a non-stem cell which can morph into a different type of cell, in these cells is pivotal for this species' changing life cycle.
