Lamellibrachia is a
L. luymesi provides the bacteria with hydrogen sulfide and oxygen by taking them up from the environment and binding them to a specialized hemoglobin molecule. Unlike the tube worms that live at hydrothermal vents, L. luymesi uses a posterior extension of its body called the root to take up hydrogen sulfide from the seep sediments. L. luymesi may also help fuel the generation of sulfide by excreting sulfate through its root into the sediments below the aggregations.[3]
The most well-known seeps where L. luymesi lives are in the northern Gulf of Mexico from 500 to 800 m depth. This tube worm can reach lengths over 3 m (10 ft), and grows very slowly, with individuals living to be over 250 years old.[4] It forms a biodiverse habitat by creating large aggregations of hundreds to thousands of individuals. Living in these aggregations are over 100 different species of animals, many of which are found only at these depths.[4]
While most species of vestimentiferan tubeworms live in deep waters below the photic zone, L. satsuma was discovered in Kagoshima Bay, Kagoshima at a depth of only 82 m, the shallowest depth record for a vestimentiferan.[5]
