Serpulidae
The Serpulidae are a family (biology), family of Sessility (zoology), sessile, tube worm (body plan), tube-building annelid worms in the class Polychaeta. The members of this family differ from other Sabellidae, sabellid tube worms in that they have a specialized Operculum (animal), operculum that blocks the entrance of their tubes when they withdraw into the tubes. In addition, serpulids secrete tubes of calcium carbonate. Serpulids are the most important biomineralising polychaetes, biomineralizers among annelids. About 300 species in the family Serpulidae are known, all but one of which live in saline waters. The earliest serpulids are known from the Permian (Wordian to lopingian, late Permian). The blood of most species of serpulid and sabellid worms contains the oxygen-binding pigment chlorocruorin. This is used to transport oxygen to the tissues. It has an affinity for carbon monoxide which is 570 times as strong as that of the haemoglobin found in human blood. Empty serpul ...
