Extremophiles Beneath Earth's Surface

Scientists from the U.S. department of energy's berkeley lab have found extremophiles living almost two miles beneath the Earth's surface. This bacterium is called Desulforudis audaxviator. This is Latin for "Descend, bold traveler and you will attain the center of the Earth"! These extemophiles are about the length of four pieces of dust. It has a flagellum (a thin tail) that it uses to swim around. This exptremophile lives off of the hydrogen the Earth produces (for respiration), and off of sulfur compounds (they use these for food). These bacteria are extraordinary because living in 'normal' conditions would kill it. There is no sunlight or oxygen down there, and because these bacteria have evolved there sunlight or oxygen would kill this bacteria. It thrives on radioactive uranium, and lives in a hot climate (the water is lives in hovers at about 140 degrees fahrenheit! These extremophiles are the king of the kingdom where they live because they are the only known species that lives in this environment. (In fact they are the only known species of life taht lives totally isolated from other living things!)
