Tumblr, meet my new obsession.
This beauty’s name is Turritopsis Nutricula, the immortal jellyfish. When it completes it’s life cycle it does something called transdifferentiation. Which, for a human would be pretty much like bending over backwards and sticking your head into your ass so hard all that’s left is a baby (really, that’s not even a bad analogy). Scientists can’t think of any reason that this process cannot be done an infinite amount of times, making it essentially immortal.
I’m almost 100% sure that I’m going to include it in my ouroboros upcoming tat (how could I not?) Sketch on the way.
