"Gas hydrate seeps are patches of seafloor that releases large amounts of gasses, such as methane; the newly discovered site is more than a mile deeper than any previously documented gas hydrate."

Study reveals close host–symbiont interactions in deep-sea chemosynthetic tubeworm

Vestimentiferan tubeworms, unique deep-sea dwellers lacking a digestive system, rely on a symbiotic partnership with sulfide-oxidizing endosymbiotic bacteria (endosymbionts) for nutrients. Living in chemosynthetic ecosystems like hydrothermal vents and cold-seeps, these worms house the endosymbionts in a specialized organ, facilitating gas exchange to fuel the microbes' organic matter production, leading to the tubeworms' remarkable growth and dense communities.

"New #ecosystem has been discovered in #volcanic cavities beneath #HydrothermalVents at a well-studied #undersea #volcano on the #EastPacificRise off #CentralAmerica. The landmark 30-day expedition aboard #ResearchVessel Falkor (too) was led by Dr. Monika Bright... Using a #robot, they overturned chunks of volcanic crust, discovering #cave systems teeming with #worms, #snails, and #chemosynthetic #bacteria"
