Cirratulids are deposit feeders which gather food from the sea bottom by means of their palps. They are sluggish worms which bury themselves below the surface of sea bottoms leaving only their gills and palps visible. Some are free-living and inhabit tubes, while others are capable of burrowing through corals, shell or rock. Hence, they occur both in shallow water as well as deep sea. They inhabit mud flats or muddy areas between rocks. They are usually orange or bright red and are found among mussels and kelps. They are indirect deposit-feeders. They have no proboscis as their food are collected by their palps and carried to the prostomium.Only suitable sized particles are ingested while others are rejected at the mouth.
