The Serpulidae are a family of sessile, tube-building annelid worms in the class Polychaeta. The members of this family differ from other sabellid tube worms in that they've a specialized 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 an important biomineralizers amongst annelids. About 300 species in the family Serpulidae are identified, all but certainly one of which live in saline waters. The blood of most species of serpulid and sabellid worms contains 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 sometimes be confused with the shells of a family of marine gastropod mollusks, the Vermetidae or worm snails. The obvious distinction is that serpulid shells are dull inside, whereas the molluscan vermetid shells are shiny inside.
