The Serpulidae are a family of sessile, tube-building annelid worms in the class Polychaeta. The members of this household differ from other sabellid tube worms in that they have a specialised operculum that blocks the entrance of their tubes once they withdraw into the tubes. As well as, serpulids secrete tubes of calcium carbonate. Serpulids are the most important biomineralizers among annelids. About 300 species in the family Serpulidae are identified, all but one among which stay in saline waters. The blood of most species of serpulid and sabellid worms incorporates the oxygen-binding pigment chlorocruorin. That is used to transport oxygen to the tissues. It has an affinity for carbon monoxide which is 570 times as sturdy as that of the haemoglobin present in human blood oxygen monitor. Empty serpulid shells can generally be confused with the shells of a household of marine gastropod mollusks, the Vermetidae or worm snails. The obvious difference is that serpulid shells are dull inside, whereas the molluscan vermetid shells are shiny inside.
