Jessica Mitchell et al.: Co-expression analysis reveals distinct alliances around two carbon fixation pathways in #hydrothermal vent symbionts https://www.nature.com/articles/s41564-024-01704-y

"#CarbonFixation is the process of converting #CarbonDioxide to sugars - the primary process that keeps our #biosphere running... In the #DeepSea, #Riftia's symbionts use energy from hydrogen sulfide to fix #carbon."

"Averaging, and at times exceeding, blackened submarine depths of 2500 meters, the #Riftia tube worm flourishes in thrumming cities of chiton; their interlocking cabled architectures capped by crimson groves of labial, lipstick-like protuberances (the hemoglobin-rich gill structures used for harvesting vented sulfide)."

Dr. Monika Bright: "The question of how #Riftia #larvae settle has puzzled me for a long time. #Tubeworms live on warm vents where fluid emerges from the cracks below. A tiny larva cannot swim against this water flow to settle from above. I hypothesize that the larvae may either settle when drifting at the bottom or settle from below. If they settle from below, then they must get sucked into the Earth`s crust to emerge from a vent."
