Editing Polychaete (section)

== Notable polychaetes ==
*One notable polychaete, the [[Pompeii worm]] (''Alvinella pompejana''), is endemic to the [[hydrothermal vent]]s of the Pacific Ocean. Pompeii worms are among the most heat-tolerant complex animals known.
*A recently discovered genus, ''[[Osedax]]'', includes a species nicknamed the "[[bone-eating snot flower]]".<ref name="BBCNews_Science&Environment_18Oct2005_Osedaxspp">{{cite news|url=http://news.bbc.co.uk/2/hi/4354286.stm|title='Zombie worms' found off Sweden |date=18 October 2005|work=[[BBC News]]|access-date=12 February 2010}}</ref>
*Another remarkable polychaete is ''[[Hesiocaeca methanicola]]'', which lives on [[methane clathrate]] deposits.
*''[[Lamellibrachia luymesi]]'' is a [[cold seep]] [[tube worm (body plan)|tube worm]] that reaches lengths of over 3 m and may be the most long-lived annelid, being over 250 years old. 
*A still unclassified multilegged predatory polychaete worm was identified only by observation from the underwater vehicle [[Nereus (underwater vehicle)|''Nereus'']] at the bottom of the [[Challenger Deep]], the greatest depth in the oceans, near {{cvt|10,902|m|ft}} in depth. It was about an inch long visually, but the probe failed to capture it, so it could not be studied in detail.<ref>[http://ns.gov.gu/geography.html Accessed Oct. 8, 2009] {{Webarchive|url=https://web.archive.org/web/19961027163532/http://ns.gov.gu/geography.html |date=1996-10-27 }} Geography of the ocean floor near Guam with some notes on exploration of the Challenger Deep.</ref>
*The Bobbit worm (''[[Eunice aphroditois]]'') is a predatory species that can achieve a length of {{convert|3|m|ft|0|abbr=on}}), with an average diameter of {{convert|25|mm|in|0|abbr=on}}.
*''Dimorphilus gyrociliatus'' has the smallest known genome of any annelid. The species shows extreme [[sexual dimorphism]]. Females measure ~1 mm long and have simplified bodies containing six segments, a reduced coelom, and no appendages, parapodia, or chaetae. The males are only 50 μm long and consist of just a few hundred cells. They lack a digestive system and have just 68 neurons, and only live for roughly a week.<ref>[https://ecoevocommunity.nature.com/posts/a-tiny-worm-sheds-light-into-genome-compaction A tiny worm sheds light into genome compaction]</ref><ref>{{cite journal | doi=10.1038/s41559-020-01327-6 | title=Conservative route to genome compaction in a miniature annelid | year=2020 | last1=Martín-Durán | first1=José M. | last2=Vellutini | first2=Bruno C. | last3=Marlétaz | first3=Ferdinand | last4=Cetrangolo | first4=Viviana | last5=Cvetesic | first5=Nevena | last6=Thiel | first6=Daniel | last7=Henriet | first7=Simon | last8=Grau-Bové | first8=Xavier | last9=Carrillo-Baltodano | first9=Allan M. | last10=Gu | first10=Wenjia | last11=Kerbl | first11=Alexandra | last12=Marquez | first12=Yamile | last13=Bekkouche | first13=Nicolas | last14=Chourrout | first14=Daniel | last15=Gómez-Skarmeta | first15=Jose Luis | last16=Irimia | first16=Manuel | last17=Lenhard | first17=Boris | last18=Worsaae | first18=Katrine | last19=Hejnol | first19=Andreas | journal=Nature Ecology & Evolution | volume=5 | issue=2 | pages=231–242 | pmid=33199869 | pmc=7854359 | bibcode=2020NatEE...5..231M }}</ref>
