Commonly called the Thread Worm or Spaghetti Worm. Most of these
worms usually conceal themselves in the sand or a crevice in the
rock, and live inside a chitonous tube surrounded by grains of
sand. Their body remains hidden inside its tube, yet numerous
thread-like filaments are fed out into the surrounding water to
trap food. Very small food particles/detritus stick to the
filaments where cilia on its thread-like tentacles draw
particles of matter to its mouth. They are basically harmless
detritivores and interesting to watch. Found both in the Indo-
Pacific Ocean and Caribbean and are valuable additions to most
sandbeds. Please click on the species you are interested in
