the research was published in the open access journal zookeys .
in fact , so far the hades and persephone centipedes are the only two geophilomorphs that have adapted to live exclusively in caves , thus rightfully bearing the titles of a queen and king of the underworld .
g. hadesi is one of only two known species of centipedes that never leave their cavernous homes .
named for the mythological god of the underworld , geophilus hadesi is a newly discovered species of centipede that inhabits the deep caves of the velebit mountains in croatia .
recorded as deep as -1100 m the new species was named geophilus hadesi , after hades , the god of the underworld in the greek mythology .
equipped with powerful jaws bearing poison glands and long curved claws allowing to grasp and tightly hold its prey , the hades centipede is among the top predators crawling in the darkness of the cave .
g. hadesi survives just fine , stoev , an associate professor of zoology at the national museum of natural history in sofia , bulgaria , and lead author of the paper detailing the new centipede species .
 
lurking in the dark vaults of some of the world 's deepest caves , the hades centipede has also had its name picked to pair another underground - dwelling relative named after persephone , the queen of the underworld .
