Sabellida
Quick Summary
The Sabellida are a diverse order of segmented marine worms, commonly known as feather-duster worms or fanworms. These sedentary polychaetes construct tubes from mud, sand, or calcareous materials. They are characterized by a crown of feathery tentacles that extend from their tubes for feeding and respiration, but are quickly retracted at any sign of danger. These tentacles trap suspended particles from the water using mucus, which are then transported to the mouth as food or used to build their tubes. Sabellids are found in both intertidal and shallow subtidal areas.1234
