Black smokers and other deep sea hydrothermal vents are present in all of the worlds oceans in areas of tectonic and volcanic activity. Although hydrothermal vents were discovered in 1977, it has only been recently that their biological and mineral importance has been recognized. Around 2,500 meters below the surface, hot water in excess of 350˚ Celsius spews a sulfide-rich mixture out from the cracks in the earths crust. When this water comes in contact with the cold bottom water (around 2˚ Celsius), the dissolved sulfides crystallize and form huge mineral rich chimneys that eventually collapse under their own weight to form crumpled mineral rich mounds on the ocean floor. InteTrestingly, such a hostile environment supports a thriving ecosystem that some scientists have perhaps overeagerly characterized as the ocean’s rainforests. Scientists, generally find upwards of 100 interconnected species, living off of energy created from chemosynthesis. Because of the toxic conditions, extremes of temperature and pressure, and absence of sunlight,
