Cut off from the rest of the world 5.5 million years ago, the Movile Cave has developed a unique and bizarre ecosystem.
It sits just a few miles from the Black Sea coast in Romania, and it is one of the most isolated places on the planet.
But the harshness of the environment hasn’t deterred scientists from exploring it.
They have discovered that it is home to a multitude of strange species, adapted to the unique atmosphere created by the cave’s isolation.
Many of the creatures have no eyes because, well, why need artificial colors or functioning eyes when you live in the dark?
Instead of photosynthesis, the inhabitants of the cave rely upon chemosynthesis, a form of life that can only be found in areas with very limited sunlight and very low oxygen.
