The deepest-ever-dwelling species of centipede has been recently discovered by scientists. It's a kind of gross similar to all centipedes. It has been named Geophilus hadesi, after Hades, the god of the underworld. Details of the new species have been published in a ZooKeys paper.

The researchers found the species in Velebit, a massive mountain that stretches over 90 miles in the Dinaric Karst. The hellion was spotted more than 3,500 feet deep beneath the surface of the Earth in Coatia. Lead study author Pavel Stoev of the National Museum of Natural History, Sofia, said in a statement that he realized immediately after seeing the animal that it was a new, hitherto unnamed and highly adapted to cave environment species.

"This finding comes to prove once again how little we know about the life in caves, where even in the best prospected areas, one can still find incredible animals", he added

The discovery marked the deepest for any centipede ever seen making its home. These centipedes have long curved claws to get a good hold of their prey. Besides, their powerful jaws have some kind of poison on them and also have an antenna to find prey even in the dark subterranean conditions.

The first discovery of Geophilus persephones happened in a cave in France during the 1990s. Humans do not need to be scared of the creature as its bite is only lethal for its prey, and causes no harm to human beings.
