Eupolymnia, commonly known as the spaghetti worm, is a genus of marine polychaete worms in the family Terebellidae. The body of a spaghetti worm is elongated, soft, and segmented, usually hidden within a tube or burrow made of sand, mucus, and debris. What makes them especially distinctive is the mass of long, thin, threadlike tentacles that radiate outward from the head. These tentacles—often white, orange, or translucent—can extend many times the length of the worm’s body and resemble strands of spaghetti spread across the substrate. These tentacles are specialized feeding structures. They creep slowly over the surrounding surface, collecting organic particles, detritus, and microscopic food.
