Immortality it’s possible. At least for the Turritopsis dohrnii, popularly known as the immortal jellyfish. Silently invading our waters, this creature will reproduce and then, faced with the normal career path of dying, it will opt instead to revert to a sexually immature stage. And not just once: it will do it over and over again, eternally flowing into the sea. With no organs or brain to focus on, the only way to research on this creature is by observing its movements that constantly repeat.
