Hydrothermal Worm Viewed Under An Electron Microscope

Huffpost Green, 7/18/11, has a short feature by Dean Praetorius showing a wonderful image of a hydrothermal worm taken using an electron microscope. The small version at the left does not do justice to the original. They say: "Taken using an FEI Quanta SEM, this image is amazingly zoomed in 525 times. The real width of the field in the image is 568μm, or 568/1000 of a millimeter. It's far larger than an atom, but still among the smallest living things. The worm, as scary as it looks, is something most people will never actually get to see (or have to worry about, for that matter). Hydrothermal worms are deep sea creatures, almost as small as bacterium, and are largely found near hydrothermal vents in the ocean.

This shot was captured by Philippe Crassous and submitted to FEI's gallery. Other amazing shots taken using FEI's microscopes can be seen here."
