Scientists discovered Geophilus hadesi more than 1,000 meters underground in damp, nearly freezing caves in central Croatia. The centipede is just under 3 centimeters long and has 33 pairs of legs, plus unusually long antennae. Researchers spotted one centipede at 1,100 meters deep — which breaks the record for deepest-dwelling centipede.
The new species was named after Hades, the Greek god of the underworld. One of the centipede’s close relatives is also known to live deep within caves: Geophilus persephones, named after Hades’ wife.
