Life at Vents and Seeps (Life in Extreme Environments)

Many of Earth's ecosystems are characterized by "extreme" environmental conditions, because they deviate from those conditions that humans would consider "normal" with regard to temperature, water availability, pressure, salinity, nutrient supply and so on. Vents and Seeps, especially deep-sea hydrothermal vents, are synonyms for life under extreme conditions because they exhibit everything that we, as surface-dwelling humans, consider extreme: high temperature, high pressure, in some cases high concentrations of toxic compounds.
