What types of worms are found on beaches?

Beaches often host various types of worms, including sandworms (such as the Nereis species), which are commonly found in sandy substrates, and lugworms (Arenicola marina), known for their burrowing habits. Additionally, sea worms like polychaetes can be found in tidal zones. These worms play essential roles in the beach ecosystem, aiding in sediment aeration and nutrient cycling.
