Olm Salamander
Despite the horrors and strangeness we’ve mentioned in the circumstances above, not all caves are filled with gruesome stores. If you’re lucky enough, it’s possible to stumble upon the natural beauty found within the depths of caves. This is specifically true for the Olm Salamander, which is a recent discovery that fascinated the scientific community. This adorable and unusual amphibian can be found in Slovenia and Croatia, and can stay for as long as a hundred years. They retain the same set of gills throughout those hundred years and they also happen to be completely blind, using their electro-sensation to feel around their environment.
Movile Cave: Part 1
Romania is specifically known for having spooky and supernatural folklore. However, what you’re about to hear in the city of Constanta isn’t supernatural even in the slightest. A cave called Movile Cave has been releasing hydrogen sulfide inside the cave for over 5 million years. This is not just horrifying to hear, but it’s unbearable. It’s no longer a shock that living organisms are incapable of withstanding this specific cave. Although, certain species belonging to centipedes and arachnids are unaffected by the cave’s conditions and have made it their home.
