The significant presence of degenerative and apoptotic processes could be related to the occurrence of a sort of metamorphosis when an adult medusa transforms itself into a polyp. 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. https://doi.org/10.1016/S0040-8166(03)00028-4.

This adaptive trait likely evolved in order to extend the life of the individual. Turritopsis nutricula is a small hydrozoan that once reaching adulthood, can transfer its cells back to childhood. And its a Medusozoa, or more familiarly known as a Jellyfish. Several different species of the genus Turritopsis were formerly classified as T. nutricula, including the "immortal jellyfish" which is now classified as T. dohrnii. Therefore, the animal is having prime importance in basic biological, aging, and biomedical researches. Probably this will be subject of discussions, but because so far in the Russian wikipedia T nutricula redirects to the Turritopsis genus you should've let the languages links there.
