There are several habitats once thought to be inhospitable to even the world's most adaptable organisms — places like the core of Chile's Atacama Desert, the driest region on Earth; ice sheet plateaus in Greenland that are 10,000 feet thick; and
near hydrothermal vents on the ocean floor with temperatures above 750 degrees Fahrenheit, to name a few.
Hydrothermal vents are located several miles below the surface,
on the
ocean floor, where the surrounding water is at or
near freezing, it is absolutely dark and the pressure is high.
