Turritopsis dohrnii, also known as the immortal jellyfish, is a species of small, biologically immortal jelly fish 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.
Like most other hydrozoans, Turritopsis dohrnii begin their life as tiny, free-swimming larvae known as planulae . As a planula settles down, it gives rise to a colony of polyps that are attached to the sea-floor. All the polyps and jellyfish arising from a single planula are genetically identical clones. The polyps form into an extensively branched form, which is not commonly seen in most jellyfish. Jellyfish, also known as medusae, then bud off these polyps and continue their life in a free-swimming form, eventually becoming sexually mature. When sexually mature they have been known to prey on other jellyfish species at a rapid pace. If a T. dohrnii jellyfish is exposed to environmental stress or physical assault, or is sick or old, it can revert to the polyp stage, forming a new polyp colony. It does this through the cell development process of trans differentiation , which alters the differentiated states the cell and transforms them into new types of cells.
The capability of biological immortality with no maximum lifespan makes Turritopsi dohrnii an important target of basic biological, aging and pharmaceutical research.
