Habitat Turritopsis dohrnii was first discovered in the Mediterranean Sea, but has since spread worldwide. T. dohrnii is generally found living in temperate to tropical waters. They can be found in marinas or docks, on vessel hulls, and on the ocean floor. They typically live in a salinity range of polyhaline (18-30 PSU) and euhaline (30-40 PSU). May 4, 2015 · Turritopsis dohrnii, the so-called "immortal jellyfish," can hit the reset button and revert to an earlier developmental stage if it is injured or otherwise threatened. 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 ... Research on T. dohrnii and Hydra polyps provides irrefutable evidence of the importance of stem cells in longevity. And last but not least, experiments on such specific organism like Hydra provide a unique opportunity to make direct genetic and functional comparisons between non-aging and induced aging organisms. and 10 variants unique for T. dohrnii or T. rubra, which were then classified into the 9 hallmarks of aging (3), depending on the affected genes (Fig. 2 and SI Appendix, section 3.3 and Fig. S3 and Tables S4–S9).
