WebBacteria at hydrothermal vents inhabit almost everything: rocks, the seafloor, even the inside of animals like mussels. All are living under extreme pressure and temperature changes. Perhaps the oddest and toughest bacteria at vents are the heat-loving ‘thermophiles.’ Temperatures well above 662°F (350°C) are not uncommon at vents.
