Feather Duster Worm

Real name is Sabellidae, but nick named after a feather duster for its unique shape and almost identicfal to a underwater feather duster. Feather duster worms are members of the Phylum annelida, the segmented worms, which includes the common earthworm. The feather dusters belong to the class Polychaeta, one of the four classes of annelids. They build tubes out of parchment, sand, and bits of shell. An insteresting fact is that Feather duster worms reproduce both sexually and asexually. Sexual reproduction involves the release of gametes into the water where the fertilized eggs develop into free-swimming larvae that eventually settle in an appropriate habitat.
      Also they periodically shed their crown, leaving the novice aquarist horrified and believing the precious creature has died. These species occur only where they typically receive moderately strong laminar water currents, and typically do not stay in the same area their whole life.
