The Spaghetti Worm (Loimia ochracea) is just one of the many thousands of different species of polychaete worms that live in the ocean. This species is about 2-3 cm in length and lives in a buried tube that it constructs from sand. It spreads its white tentacles over the sandy sea floor to draw in food particles to its mouth. The tentacles contain chemical compounds that make them unpalatable to fish.
