Lamellibrachia satsuma (also known as Satsuma tubeworm or Satsumahaorimushi or {{Nihongo||サツマハオリムシ|Satsuma Haorimushi}}) is a vestimentiferan tube worm that was discovered near a hydrothermal vent in Kagoshima Bay, Kagoshima at the depth of only {{convert|82|m|abbr=on}} the shallowest depth record for a vestimentiferan. Its symbiotic sulfur oxidizer bacteria have been characterised as ε-Proteobacteria and γ-Proteobacteria.{{cite journal|last1=Patra |first1= A.K. |last2= Cho |first2= H.H. |last3= Kwon |first3= Y.M. |first4=K.K.|last4= Kwon|first5= T. |last5= Sato|first6=C. |last6=Kato |first7=S.G. |last7=Kang |first8= S. |last8=Kim |title=Phylogenetic relationship between symbionts of tubeworm Lamellibrachia satsuma and the sediment microbial community in Kagoshima Bay. |journal=Ocean Science Journal |volume=51 |pages=317–332 |year=2016|issue= 3 |doi=10.1007/s12601-016-0028-6 |bibcode= 2016OSJ....51..317P |s2cid= 88820473 |url=https://link.springer.com/article/10.1007/s12601-016-0028-6|url-access=subscription }} Subspecies have been later found associated with cold seeps at Hatsushima in Sagami Bay and at the Daini Tenryu Knoll in the Nankai Trough with specimens obtained at up to {{convert|1170|m|abbr=on}} depth.{{cite journal|journal=Zootaxa|first1=Genki |last1=Kobayashi |first2=Tomoyuki |last2=Miura |first3=Shigeaki |last3=Kojima |title=Lamellibrachia sagami sp. nov., a new vestimentiferan tubeworm (Annelida: Siboglinidae) from Sagami Bay and several sites in the northwestern Pacific Ocean|volume=4018 |issue=1|date=2015-09-14|pages=97–108 | doi=10.11646/zootaxa.4018.1.5 |pmid=26624030 |url=https://www.biotaxa.org/Zootaxa/article/view/zootaxa.4018.1.5|url-access=subscription }}
