Kagoshima Bay
In Kagoshima Bay, there are methane gas seepages called "tagiri" (boiling). "Lamellibrachia satsuma" live around there. The depth of this site is only 80 m, which is the shallowest point Siboglinidae living. "L. satsuma" may be kept in an aquarium for a long period in 1 atm. Two aquariums in Japan are keeping and displaying "L. satsuma". An observation method to introduce it into a transparent vinyl tube is being developed.
