Turritopsis dohrnii
Introduction
Turritopsis dohrnii (previously classified as Turritopsis nutricula)[1], commonly known as the immortal jellyfish or the Benjamin Button jellyfish,[2] is a small species of jellyfish known for its unique ability to revert back to an earlier life stage through transdifferentiation.[3][4] This ontogeny reversal renders the organism virtually immortal as this process has the potential to repeat itself indefinitely, although organismal death does still occur in its natural environment.[5] Reverse development can be triggered by a variety of stressors including starvation, changes in temperature or salinity, physical damage, or age-related deterioration.[4]
Although a rare ability, reverse development has been reported in several other Cnidaria species. Some of these include Laodicea undulata,[6] Aurelia sp.,[7] Hydractinia carnea,[3] Podocoryne carnea, Eleutheria dichotoma, Cladonema sp. and Cladonema uchidai, and Perarella schneideri.[5]
