Gloomworms are very simple worms that swim around in dark caves. They live on bacteria and are eaten by just about anything else in the cave. All the species of worm here except the garden worm, which evolved from convoluta worms, are descended from a common ancestor, a bristleworm that survived the mass extinction by living in caves. Its family is bacteriophagidae.
