The world’s deepest-dwelling centipede — found as much as 3,600 feet below the surface — is in Croatia, a new study in ZooKeys reports. The centipede was found in three caves in the Velebit mountain range, along the Adriatic Coast. It has powerful jaws with poison glands and long, curved claws that allow it to clutch its prey. And like other cave-dwelling arthropods, it has elongated antennas, trunk segments and leg claws. Researchers named the centipede Geophilus hadesi, after Hades, the Greek god of the underworld.
