Sabellastarte spectabilis
''Sabellastarte spectabilis'' is a species of benthic marine polychaete worm in the Sabellidae family. It is commonly known as the feather duster worm, feather duster or fan worm.〔(Introduced marine species of Hawaii )〕 It is native to tropical waters of the Indo-Pacific but has spread to other parts of the world. It is popular in aquariums because of its distinctive appearance and its ability to remove organic particles and improve water quality.〔(Fan Worms & Feather Dusters (Annelids) )〕
Polychaetes, or marine bristle worms, have elongated bodies divided into many segments. Each segment may bear setae (bristles) and parapodia (paddle-like appendages). Some species live freely, either swimming, crawling or burrowing, and these are known as "errant". Others live permanently in tubes, either calcareous or parchment-like, and these are known as "sedentary".
==Taxonomy==
This worm has a complex taxonomic history. It was known as ''Sabellastarte sanctijosephi'' when it first appeared in Hawaii in the 20th century.〔 The names ''S. punctata'' and ''S. indica'' were used by Hartman (1966) 〔Hartman, O. 1966. Polychaetous annelids of the Hawaiian Islands. Occ. Pap. B.P. Bishop Mus. 33(11): 163–252. 〕 and others. In 2003 Knight-Jones and Mackie undertook a revision of the genus ''Sabellastarte'' and determined that ''Sabellastarte spectabilis'' was the correct name.〔(A revision of ''Sabellastarte'' (Polychaeta: Sabellidae) )〕
