Thermophilic bacteria. Collected in the summer of 2012 in 60C water in Yellowstone National Park, Wyoming USA. This scanning electron micrograh (SEM) was shot at 19,000X magnification and the filed of view is 3 um. This type of bacteria is adapted to thrive at high water temperatures and is currently the focus of biological researchers. Bacteria that can live in these extreme conditions are called thermophiles or extremophiles..
