Genome of a biologically immortal cnidarian . The cnidarian Turritopsis dohrnii can revert to an asexual life stage after reproduction and rejuvenate itself repeatedly, making the species biologically immortal and challenging current understanding of aging. Maria Pascual-Torner, Dido Carrero, et al. report the whole genome sequences of T. dohrnii …Turritopsis dohrnii (Cnidaria, Hydrozoa) undergoes life cycle reversal to avoid death caused by physical damage, adverse environmental conditions, or aging. This unique ability has granted the species the name, the “Immortal Jellyfish”. T. dohrnii exhibits an additional developmental stage to the typical hydrozoan life cycle whichTurritopsis nutricula is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. This adaptive trait likely evolved in order to extend the life of the individual. Several different species of the genus Turritopsis were formerly classified as T. nutricula, including the "immortal jellyfish" which is now classified as T. dohrnii.This trick earned the species its nickname as the immortal jellyfish, a term Graham admits is a bit hyperbolic. The study was aimed at understanding what made this jellyfish different by comparing the genetic sequence of T dohrnii to that of Turritopsis rubra, a close genetic cousin that lacks the ability to rejuvenate after sexual reproduction.A Turritopsis dohrnii in the fully-grown medusa lifecycle stage. Immortality. During the week of Halloween, such a word seems more ascribed to vampires and ghoulish fairytales, not genetic research related to jellyfish.

Altogether, these results unveil key molecular mechanisms behind rejuvenation of T. dohrnii.T. dohrnii, like other jellyfish, may use its bell to catch its prey. T. dohrnii's bell will expand, sucking in water, as it propels itself to swim. This expansion of the bell brings potential prey in closer reach of the tentacles.[24] Predation Turritopsis dohrnii, like other jellyfish, are preyed on most commonly by other jellyfish. Other
