POMPEII WORM (Alvinella pompejana) and the microbe Nautilia profundicola who reside on their back ©University of Delaware The Pompeii worm, the most heat-tolerant animal on Earth, lives in the deep ocean at hydrothermal vents.* The worm’s back is covered in bacteria adapted for living in extreme environments The research focused on the bacterium Nautilia profundicola, a microbe that survives near deep-sea hydrothermal vents. It was found in a fleece-like lining on the backs of Pompeii worms, a type of tubeworm that lives at hydrothermal vents, and in bacterial mats on the surfaces of the vents’ chimney structures. One gene, called rgy, allows the bacterium to manufacture a protein called reverse gyrase when it encounters extremely hot fluids from the Earth’s interior released from the sea floor. “The discovery of reverse gyrase in Nautilia profundicola suggests that it plays a key role in this microbe’s ability to thrive near deep-sea hydrothermal vents, where conditions are thought to resemble those found on early Earth,” said Matt Kane, program director in the National Science Foundation (NSF)’s Division of Environmental Biology, which funded the research. “Knowledge of microbes living near vents may aid our understanding of how life evolved.” more here Fact Source: National Science Foundationhttp://en.wikipedia.org/wiki/Hydrothermal_venthttp://en.wikipedia.org/wiki/Alvinella_pompejana Other deep water/vent animals you may like: Armor Snail Polychaete Carpet Worm (gets no love) Terrible Claw - Deep Water Lobster •A hydrothermal vent is a fissure in a planet’s surface from which geothermally heated water issues.
