Nightmarish 'Demon Fire' Worms Unearthed

Scientists have discovered a new genus of glow-in-the-dark worms they call ‘demon fire’ worms, which are part of a family of worms known as bristle worms. The three newfound species are found in the shallow waters of Japanese rivers and streams. Researchers want to determine how the glow-in-the-dark worms create their bioluminescent appearance and then use that to develop a man-made type of bioluminescence. Bristle worms like these new demon fire worms have existed since the Cambrian period, over 505 million years ago.
