AOS: Обзор всех видов необычных медуз

Every Strange Jellyfish Type Explained Most animals age in one direction, deteriorating until they stop. Turritopsis dohrnii does not follow that rule. This tiny creature, no wider than four and a half millimeters across, can reverse its own aging process completely, transforming from a sexually mature adult medusa back into a juvenile polyp and restarting its life cycle from scratch. The mechanism behind this is called transdifferentiation, a process where fully specialized cells convert into entirely different cell types, something so rare in multicellular animals that scientists had essentially no framework for it when the phenomenon was first formally documented in nineteen ninety-six by marine biologist Ferdinando Boero.
