Family Chaetopteridae "tubeworms"

Distribution: Yet to be found in Singapore
The chaetopeterids known as "tubeworms" are permanent tube dwellers. Their tubes are fragile and are made of translucent chitinous material or an opaque parchment material sometimes with embedded sediment granules or attached to a rocky surface. Parchment tubes occur curved or straight forms while chitinous tubes occur in branched or simple forms. They are commonly found from intertidal to shallow waters inhabiting soft sands or mud sediments. Certain species does not use prostomial tentacles but filters particulate matter in a mucous bag strung across the U-shaped tube. The bag forms an effective filtering device as most of the water drawn into it has to pass through it. Species found in Singapore include:
  • Chaetopterus cariopedatus
