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.

Upon contact with the cold, dense ocean, the vent fluid “ precipitates ” minerals such as sulfates , sulfides , and quartz . WebHydrothermal vents form at locations where seawater meets magma. A venting black smoker emits jets of particle-laden fluids. The particles are predominantly very fine-grained sulfide minerals formed when the hot hydrothermal fluids mix with near-freezing seawater.
