Lamellibrachia satsuma , also known as Satsuma tubeworm, is a vestimentiferan tube worm that was discovered near a hydrothermal vent in Kagoshima Bay, Kagoshima at the depth of only 82 m the shallowest depth record for a vestimentiferan. Its symbiotic sulfur oxidizer bacteria have been characterised as ε-Proteobacteria and γ-Proteobacteria. 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 1,170 m depth.
