The polychaete worms (in the traditional inclusion of taxa) are mostly marine. They are commonly found burrowing in sediments on beaches, or live in tubes, which in cases where many worms live together, form calcareous reef structures. Some species are free-swimming, some live as commensals or parasites. Polychaetes are the most abundant macrofauna of the deep sea, and inhabit the world’s oceans at all different depths and water temperatures.
