Despite what you’ve been led to believe, planet Earth is practically unchartered territory. About 71% of its surface is covered in water too deep and dangerous to explore. Even on land, unexplained mysteries creep up on all sides, beneath ceilings of dangling stalactites. Caves - and the creatures that live in them - are unlike anything you've probably ever seen before. If anything, they’re more akin to space aliens and the monsters drawn up by authors of science fiction.
Creatures that only live in caves are known as troglobites or troglophiles. Troglobites are obligatory cave dwellers who cannot survive outside of this natural habitat. On the other hand, troglophiles can survive outside of these caverns, but they choose to remain within their confines for the vast majority of their lives. Crazy cave creatures are of two varieties, troglofauna (animals of the land) and stygofauna (inhabitants of the sea).
Here are some mindboggling troglobite facts that prove, once and for all, that a strange, inexplicable universe is footsteps away as opposed to light years ahead.
KauaʻI Cave Wolf Spider Is Endangered
This cave dwelling critter is blind as a bat, but he’s actually a spider. One of the strangest aspects of his anatomy is that the Kauaʻi Cave wolf spider is the only member of the big eyed spider species who doesn’t have eyes at all. Classified as a troglofauna troglobite, or land dwelling, cave-only creature, this astounding endangered spider is so rare that only three populations of its kind are known to be in existence. Conservation efforts are becoming a pivotal factor in securing this particular spider’s place on the planet. You can find the Kauaʻi Cave wolf spider scurrying through the Koloa-Poipu cave system, hunting down its favorite prey, the Kaua‘i cave amphipod, a tiny crustacean that is, unfortunately, also endangered.
This mesmerizing spider is quite distinguished in its looks. In addition to having a vacant space where eyes should be, it’s also semi transparent and earth toned with silver haired, spindly legs. In addition to population and appearance, the Kaua‘i is unique in that it lacks the characteristic most associated with spiders to begin with. It doesn’t take the time to spin a web. In order to devour prey, this eyeless, webless spider relies on its three vampire-esque, puncturing fangs and its fast, nimble legs, hunting, capturing, and consuming all in one exaggerated movement.14933Creepy?
Cave Dwelling Rat Snakes Dangle From Cave CeilingsVideo: YouTube
Of all the wonders that caves and caverns hold, who knew they would be guarded by their very own species of snake? This is certainly true of the caves in Thailand and along the Peninsular Malaysia. Cave dwelling rat snakes are a subspecies of the land dwelling beauty rat snake and they possess a similar vicious temperament. The cave dwelling variety survives on regular meals consisting of cave dwelling bats. In one particularly batty cave, these snakes that can grow four to eight feet long upon adulthood, are literally seen dangling from the ceiling on the hunt for fresh flying prey.13931Creepy?

Scientifically referred to as Eupolybothrus Cavernicolus, this troglobite got its nickname, the "Cyber-Centipede," for being the first fascinating eukaryotic organism to undergo a scientific process known as transcriptomic profiling. This means that multiple scientific data collected by way of metabarcoding about this cave dwelling centipede will be virtually accessible to the general public. In terms of the centipede itself, it is a previously undiscovered species that thus far has only been seen crawling across the landscape in the caves of the remote region of Croatia.9926Creepy?
A Hausera Has A Very Strange Body
This wormy looking guy has some of the most baffling anatomy known to man. He’s a subterranean troglobite from a family of freshwater triclads. Hausera made history when it became the first cave dwelling species of its kind to be recorded in South America. Since then, it has continued to astound the scientific community with its little oddities, which include ovaries positioned within close proximity to the brain, genitalia that seem to communicate with the intestine, and a completely eyeless body void of any sort of pigment.7727Creepy?
