Despite the extreme conditions that dominate hydrothermal vents on the East Pacific Rise and Mid Atlantic Ridge Bythograea thermydron, a eurythermal extremophile first described in 1980, lives in such high abundance that they are used as an indicator for active vent sites. Their approximate 4 year life span is spent at 2.7km below sea level at high pressure, a range of temperatures, low pH, low light intensity and sulphide levels toxic to most organisms. This essay covers the adaptations of B.thermydron
