Sabellids build tubes out of a tough, [[parchment]]-like exudate, strengthened with sand and bits of shell. Unlike the other sabellids, the genus ''[[Glomerula]]'' secretes a tube of [[calcium carbonate]] instead. Sabellidae can be found in [[subtidal]] habitats around the world. Their oldest fossils are known from the [[Early Jurassic]].<ref name=VinnMutvei2009>{{cite journal | last1= Vinn | first1= O. | last2= Mutvei | first2= H. | year = 2009 | title = Calcareous tubeworms of the Phanerozoic | journal = Estonian Journal of Earth Sciences | volume = 58 | issue = 4 | pages = 286–296 | url = http://www.kirj.ee/public/Estonian_Journal_of_Earth_Sciences/2009/issue_4/earth-2009-4-286-296.pdf | access-date = 2012-09-16 | doi=10.3176/earth.2009.4.07 | doi-access = free | bibcode= 2009EsJES..58..286V }}</ref><ref name='VinnTenHoveMutvei2008'>{{cite journal | doi = 10.1111/j.1475-4983.2008.00763.x | title = On the tube ultrastructure and origin of calcification in sabellids (Annelida, Polychaeta) | year = 2008 | author = Vinn, O. | author2 = ten Hove, H.A. | author3 = Mutvei, H. | journal = Palaeontology | volume = 51 | issue = 2 | pages = 295–301 | url = https://www.researchgate.net/publication/222089802 | access-date = 2014-06-11| doi-access = free | bibcode = 2008Palgy..51..295V }}</ref>

==Characteristics== Feather-duster worms have a crown of feeding appendages or [[radiole]]s in two fan-shaped clusters projecting from their tubes when under water. Each radiole has paired side branches making a two-edged comb for filter feeding. Most species have a narrow collar below the head. The body segments are smooth and lack [[Parapodium|parapodia]]. The usually eight thoracic segments bear capillaries dorsally and hooked [[chaeta]]e (bristles) ventrally. The abdominal segments are similar, but with the position of the capillaries and chaetae reversed. The posterior few abdominal segments may form a spoon-shaped hollow on the ventral side. Size varies between tiny and over 10&nbsp;cm (4&nbsp;in) long. Some small species can bend over and extend their tentacles to the sea floor to collect [[detritivore|detritus]].<ref>[http://www.annelida.net/nz/Polychaeta/Family/F-Sabellidae.htm NIWA Guide to Polychaeta]</ref> [[Image:Sabellidae (feather duster worm) yellow.jpg|thumb|upright|right|Sabellid with feathery [[Gill|branchiae]] extended]] [[Image:Sabellidae (feather duster worm).jpg|thumb|250px|right|A sabellid, species unknown]]
