	Description:		Transcript: Many microbial organisms on Earth can survive extremes of temperature. Thermophiles is the name for organisms that like heat. Thermophiles have been found that can exist in the temperature range forty-two to a hundred and thirteen degrees centigrade. That's a hundred and seven to two hundred and thirty-six degrees Fahrenheit, well above the boiling point of water. Examples of these organisms are found near deep sea geothermal vents and in Yellowstone National Park. At the opposite extreme are psycrophiles, creatures or organisms that like extreme cold. Psycrophiles have been found in the temperature range down to minus three degrees centigrade up to twenty degrees centigrade. That is creatures that like to live below the freezing point of water. These have been found in snow fields in Antarctica, on the surface of glaciers, and in the deep sea ocean far from vents where the temperature is very cold.
