One example of commensalism is the relationship between Patiria miniata, known as the Bat star, and a segmented worm called Ophiodromus pugettensis. The star has several grooves protruding from its mouth. Some Ophiodromus pugettensis worms live inside these grooves, but they do not harm the starfish.
