      Serpulidae is a family of sessile, tube-building annelid worms in the class Polychaeta. The members of this family differ from the sabellid tube worms in that they have a specialized operculum that blocks the entrance of their tubes when they withdraw into the tubes. In addition, serpulids secrete tubes of calcium carbonate. Serpulids are most important biomineralizers among annelids. There are about 300 known species in the Serpulidae family, all but one of which live in saline waters. The earliest serpulids are known from the Middle Triassic.[1]

      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.[2]

      Empty serpulid shells can sometimes be confused with the shells of a family of marine gastropod mollusks, the Vermetidae. The most obvious difference is that serpulid shells are dull inside, whereas the molluscan vermetid shells are shiny inside.
