People have always wondered what the secret to immortality is. This jellyfish has found the answer to that and the answer is having the lack of maturity. The scientific name is Turritopsis dohrnii but I am going to call it the immortal jellyfish. Biologically, they can be found in the Mediterranean Sea and in Japan.

Christian Sommer discovered the creature in 1988 while conducting research on hydrozoans, small invertebrates that, depending on their stage in the life cycle, resemble either a jellyfish or a soft coral. When he put his specimens in petri dishes to record their reproductive habits he noticed that the Turritopsis dohrnii were acting very peculiar. They simply refused to die, they appeared to age in reverse until it reached its earliest stage of development, where it started its life cycle again. It was about a decade later when people decided to use the word “immortal’ to describe the animal.

I am going to tell you some fun facts about the Turritopsis dohrnii. Their diet consists of plankton, fish eggs, and small mollusks. They are quite small (2.5cm) they do sting but they are not poisonous.
Though most species are genetically identical, some of them have adapted to their environment. Some of them that live in the tropics have 8 tentacles while ones from temperate areas have 24 tentacles.

Those are some facts about the immortal jellyfish. They are very interesting in the sense that they can practically live forever.
