Turritopsis dohrnii, commonly known as the immortal jellyfish or the Benjamin Button jellyfish[1], is a small species of jellyfish known for its unique ability to revert back to an earlier life stage through transdifferentiation after reaching sexual maturity[2][3]. 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[4]. Reverse development can be triggered by a variety of stressors including starvation, changes in temperature or salinity, physical damage, or age-related deterioration>[5].
